Packaged LDAP Authentication [SOLVED]16 users found helpful
Though this has worked flawlessly for me, I would hesitate implementation in a production environment at this point.
When installed, the original login page is deleted and replaced. However, upon uninstall, the original settings are restored. This is a less than desirable, but makes for a seamless implementation of support for LDAP authentication.
Until we get native support for third party authentication protocols, this has been the only method I've found that will work, aside from modifying core files.
When you try to login, c5 will ask the LDAP host to authenticate the user's credentials. If the user is not already in the c5 database, a new user profile is create with the provided username and password.
As a fail-over, if the LDAP host is unreachable, the c5 database will be used to authenticate the user by using the last working password authenticated by the LDAP host (it's updated every login).
No users will be deleted upon install or uninstall, however, if a user with the same username exists, their password WILL be overwritten by the last password authenticated by the LDAP host.
Quick shout-out of thanks goes out to Andrew.
Questions, comments and requests are welcomed!
At this point I would not recommend using this package, however, I am leaving it here as a reference to anyone that wants to see how it works.
The authentication method works well, but the way the Login page gets replaced when the package is installed is quite intrusive to the c5 core and can make things unstable in certain environments.
A package was funded and entitled an MIT license that provides LDAP Authentication support. Thanks goes to Cascadia Behavioral Health Care for the project funding and the allowance of an MIT license.
At some point I'll get this up on the MarketPlace, but for now...
[EDIT 3 - Dec. 30th, 2012]
Latest version is now compatible with versions 184.108.40.206 and below.
[EDIT 4 - Sept. 25, 2014]
Reinhilde Kircher (strawberry) has been kind enough to update the code to work with nested groups. The attached file name is ldap_authenticator.zip.
It should be noted that I have not tested it in any capacity. However, to get it to work, you'll need to replace the ldap_authenticator.php file in the "helper" folder with Reinhilde's new version.
I haven't had time to work on it in the past week, but I'll eventually get it Market worthy.
The most difficult part is understanding the LDAP Base Query. I'd like to integrate a way to easily generate one for you, but I've got a huge-mongous project on my hands at the moment, and just needed some quick and dirty LDAP authentication for c5 that's easily portable to other instances.
For now you'll need to use something like: CN=YourGroup,OU=Users,DC=YourDomain,DC=com
I'm actually still waiting for the next c5 core to support 3rd party authentication. Then I'll write a 'real' package.
Packages exist now, but they are hacked together - so to speak. However, from what I understand, there are plans to make packaging authentication add-ons much easier and with tighter integration.
You'll see free add-ons of this nature, but likely cripple-ware compared to versions you have to pay for. And you'll only see those because the select few developers feel they have a moral obligation to give back to the community. Open source communities start failing when people just take, take, take and don't give back.
Case and point, what I released. It works, but you need to know how to work with LDAP in order to get it to work right. Where as a paid version would make it so my 14 year old brother could manage it.
There are a ton of c5 fanboys here that would love to see everyone move this direction (myself included). But it's hard to work for free, ya know?
I mean, I assume you get paid for your work, right? And I'm sure it's been a task to find a CMS worth using with the features you want/need. Cross platform development is painful. Compensation is necessary.
Now, about the LDAP integration. Arrrgggh!
I've been experimenting with it and it does look a bit hairy, but doable. If I come up with something better than an cursory experiment I'll try to remember to post my findings.
Any thoughts on this?
I need to be hitting LDAP on every login, successful or not, in order to check the user's AD credentials/groups to see if they've changed since the last login. The try statement at line 157 seems to me that if the user exists, then move on; and the LDAP query specified in the else case started at line 166 is never executed.
Or, as I said earlier, I'm just reading the code wrong, which could easily be the case. I'm much more comfortable with procedural/function code than OOP code.
1. In line 137, the script first tries to authenticate the user using local information from the MySQL database (concrete5 userbase). If that authentication is successful, the script moves on and never queries LDAP.
2. If the login in line 137 is unsuccessful, the script first checks the cause of the failure: non validated user or whether he used an invalid email address. If all this fails, we are in a situation where the user specified an unknown login name and password and only then are we querying LDAP.
3. The try/catch from line 157 to line 177 is the LDAP connection and the lines 178 - 189 are the error handling of the LDAP connection and authentication.
If you want to hit LDAP on every login (which might be dangerous since the LDAP server might be down or unresponsive), you need to modify the script and remove the local login in line 137 and only keep that section using the LDAP authentication.
1) Try to verify user/security groups first via LDAP (if successful, check to see if LDAP group membership has changed since last time, and update, but don't prevent login, just update the local MySQL groups & usergroups tables). If this is a new user, add their LDAP credentials to the local MySQL tables: users, groups, usergroups.
2) If LDAP connection fails, just check the local MySQL db for the user and their group privs, and login in with those historical credentials.
3)If THAT fails, fail the login completely and notify user that they are new and will need to wait for LDAP verification in order to login (I would think this would be a very rare occurance since it would only happen for new users and LDAP would have to fail).
So with that, I know I will need to re-code this portion of the app. Thanks for the heads-up!
Am I reading that right? I only see do_login() getting called from the change_password() function, which itself is only called from the forgot_password() function. And I think, but I'm not sure, that forgot_password() is only getting called when an unrecognized User/PW is encountered by the openID stuff. ??? I think maybe I'm missing something here?
Fatal error: Cannot redeclare class PageNotFoundController in D:\Inetpub\konnect.konstant.com\concrete\controllers\page_not_found.php on line 12
Any help would be much appreciated!
I honestly haven't looked at the package in a while so I'm not sure what could be causing the issue.
Something is initialising the PageNotFound class from my code, and then it gets initialised again by something else... or vise versa.
As I had quite a few problems with your package, i'd like to share a few points that I feel are important to mention:
1. I installed your plugin on an Ubuntu server with that MySQL distribution that comes along Ubuntu. The default behavior of such an installation is that table names are case-sensitive. This is problematic since you use the table "config" quite a lot in your queries even though the correct name would be "Config". I had to change this before I could even get your package to work.
2. In the file ldap_login/controllers/ldap_login on line 186, where you implement your custom error-reporting messages, you access the field "msg" of object $e. This field was empty for me and the correct method would be to use $e->getMessage()
3. In the same file in line 174, you use the static function UserInfo::register to add a new user. Since I'm not very familiar with the concrete5 API, I looked it up but couldn't find the register method in the API (http://www.concrete5.org/documentation/developers/permissions/users) Maybe this method is deprecated (?) and I replaced it with UserInfo::add() as mentioned in the API.
4. Finally, I stumbled upon a huge problem: in our LDAP, we have our users distributed over several organizational units (OU). If I specify a OU in the Base Query such as: "OU=xxx,DC=yyy,DC=zzz" I can authenticate with any user and retrieve information from users in that OU. This is however not what I wanted since I need all the users from all the OU. Leaving out the "OU=xxx" part from the Base query, I could authenticate with any user but not retrieve any user information. Even after setting the LDAP_OPT_REFERRALS to false, the behavior was the same. I eventually concluded that it was a problem with adodb and after i completely replaced adodb with native php5-ldap functions, it worked flawlessly!
In the end, I used these two lines to find user information from any user regardless his OU:
$filter = "(&(objectCategory=person)(sAMAccountName=" . $this->post('uName'). "))"; $result = ldap_search($ds, $ladp_config['LDAP_BASE'], $filter);
Thanks for your help and keep up the good work!
(Thanks for the info to my query above, btw)
In my case, for your issue #1, on a Win2K8 WAMP stack, the MySQL tables were all lowercase. Perhaps that check needs to account for both upper/lower-case possibilities.
Can't help with #2 or #3 since I did not encounter those issues.
For issue #4, it took me awhile to build a working Base Query as well. That is until I found a neat little trick. If you're logged into the AD Domain on a windows box, you can go to the cmd window and type the command gpresult and you will get all of the AD info for the logged in user. The key part being, if you scroll down to the USER SETTINGS portion, you will see the CN, OU, DC info for that user. In our setting, and perhaps yours, above the specific OU, there was a generic OU that I could use to build my Base Query.
I hope this info is helpful to you and to others wrestling with building a working Base Query.
Any ideas on why I am seeing this would me most appreciative
At this point, I would not recommend using the previously posted package.
I'll be implementing this in the next day or two, and will report any bugs or feedback from the project.
Let me know when you publish this to the marketplace - I'll happily be your first customer...! I think you'll find a good market for this as an add-on, and would expect that those who would be implementing this type of functionality would be happy to pay for a packaged solution.
It's also important to note that if there is an account in LDAP that has the same sAMAccount name as the c5 admin account, the password will update when you run the LDAP query job. I should fix this, but haven't had a chance. However, the account password does not update (like all the other accounts do) when you log in.
- Able to properly configure a base query and connect to the ldap server.
- For some reason, the config value for LDAP_FILTER didn't make it in to the database during installation. Adding it manually fixed the issue. At first glance, I can't see anything that would prohibit that config value from being added to the database.
- The LDAP poll job appears to check for matches in the active directory, and then assign a random password to each if a match is found. Is this the desired functionality?
Yes, this is the desired effect. When a user signs in with credentials validated by the LDAP server, the user's password will get updated.
A potential issue that that if there is a user in the LDAP user base that has the same username as the c5 super user (User with ID 1) it will over write make SU's password random. By default the SU doesn't get validated by the LDAP server just in case something goes wrong with the server and you need some kind of back door.
The only problem i could foresee is if the LDAP poll job runs successfully, then at a subsequent point the LDAP server becomes unavailable. The password will no longer match the previous C5 password, and the LDAP server won't be able to authenticate the user.
I've been meaning to fix the SU's password issue. I could hit two birds with one stone by just telling it to ignore existing users.
Unless you want to make the changes yourself, expect an update in the next week or so.
This has been running on a production server for about a week now. The only other change I needed to make was to overwrite the controller for the login page with the contents of the ldap_login controller. When the login page was loaded directly, everything worked properly. For some reason, when a page presented the login dialog (such as requesting the dashboard while not logged in), the request never made it to the ldap_login, and instead attempted to authenticate using the C5 user database. There have been some other customizations to this installation in the past, so this might not occur on a fresh install.
After that change, I've seen no problems whatsoever. Both the active directory and C5 user database on this server are large (1000+), and the site sees heavy traffic.
Basically it checks to see if you are on the login page, if not, the script is ignored. If you are on the login page, it executes a controller->redirect() to the ldap_login page.
It relies on Event triggers (on_start specifically, if I remember correctly), which should be enabled by default if you are using the latest version of c5.
I added a redirect in custom login.php page to force ldap login for restricted pages - crude, temporary workaround.
Thanks in advance...

This was one of the work-arounds needed since modifying the core code was not possible for this to be in a package and work with future versions of c5.
So you can follow the flow:
~/controller.php @line 42 (This runs on every single page load.)
~/models/login_redirect.php (Checks if we're on the /login page, redirects if so).
I'd like to know what you did to get it to work with your OpenLDAP. That's the same setup that I have. I have it working with LDAP setup in the Dashboard, but when I try to log into the site I get an error saying invalid username or password. I know the information is correct because I use it on the config page in the Dashboard and it connects and authenticates.
When I log on using my concrete5 ID, I'm able to log in, but for some reason my LDAP users don't authenticate.
Any help would be greatly appreciated.
What may have tripped you up is that the Username isn't just the username. It sure tripped me up. In fact, I should have probably changed that title to something that indicated it was the DN for the user.
Definitely the username got me tripped up, but it has me really tripped up now, because I don't understand why it works on the Dashboard configuration page, but the actual login page doesn't work. It appears to be using the same code, but for some reason the login page doesn't work, but the config page does. To make the Dasboard Config page work, I build the username in the code that gets passed to the LDAP server. I append the rest of the DN information to my username and that seems to work - for the Dashboard Config page, but not for the login page. It's driving me crazy.
Now I'm walking the code to figure out what is causing the Invalid Username or Passord because I can use the same username and password on the Config page and it works.
I also wanted to point out that I can't add my groups in through the dashboard. I have to add them in manually through ldap_authenticator.php.
I am running a Concrete5 website as a small non-profit intranet and ideally I'd like to use LDAP (Win 2k3 domain). I don't really have much knowledge of LDAP but I'm happy to read (and I'm pretty good with my googlefu!)
But... Perhaps I'm missing something completely... How do I configure this to find my Win 2k3 server? I'm assuming that I need to configure/define something somewhere for your addon to pick up? Would that be in the Concrete5 config/site.php file? Or do they go somewhere in your script? Or somewhere else?
After a fair bit of fiddling and reading and searching I've got nowhere. I don't expect you to give me all the answers and hold my hand, but just a little more initial config info would be awesome. I note that you said that I "need to use something like: CN=YourGroup,OU=Users,DC=YourDomain,DC=com" but where does that go? I think with just a little more info I will have a chance of getting this going... Even just an example and a location of where it has to go.
Thanks in anticipation. :)
Thanks so much!
Guess I'm just looking for a little bit more direction in terms of set up if possible for someone new to Active Directory/LDAP.
Thanks again for putting this together.
Fill in the "Poll Users Job Authentication" form.
Click "Save and Test". Make sure results are returned.
Go here: Dashboard -> System & Maintenance
Make sure the job "Poll LDAP Users" is enabled.
Click "Run Checked"
A bug with the user polling job is that it sets the "admin" account to something random. So either make sure to change the "admin" account username to a specific AD account username, or you'll have to rehash a password for the admin account every time you run the poll users job.
I am having trouble when attempting to configure the basic authentication configuration settings. When I try to save our server and ldap domain information, I get a Page not found error. The URL that is displayed (sanitized):
I noticed earlier in the thread someone else had this problem, but you had not experienced the issue before. I'm hoping in the time since that post and the information in the URL may be of assistance.
If you can't figure out how to enable short tags, you can change the code.
<?= is equivalent to <?php print
[Edit]: I'll have to take that back. Setting short_open_tag On did clear up the problem with un-parsed php in the url, but then another problem became apparent. (I'll make a separate post on it if there is nothing mentioned elsewhere in this discussion.)
I will also mention (forgive me if this has already come up) that when I was checking the recommendations for the use of short_open_tag with php.net, I came across a few caveats about the fact that this configuration option may not be supported much longer. They didn't go so far as to say it was officially deprecated, but they are recommending that we adopt the practice of always using the full tags and keeping short_open_tag set Off, due to conflicts with other platforms such as xml.
But I will say I'm very happy to have found this - it will easily solve what I thought was going to be a big challenge. Thank you for letting us try it out while you're working on it. We will also be purchasing it once it hits the marketplace.
) to skin the ldap_login page but can't seem to get it right. Any suggestions?
php_ldap installed and confirmed running - check
Package installed - check
- the LDAP Dashboard page is loading
- the Poll LDAP Users job is showing in the list of automated jobs (although I had to move poll_ldap_users.php from ../packages/ldap_auth/jobs to ../jobs before it would show up - not sure if this has anything to do with my problem or not.)
Using correct LDAP host name - think so but not 100% sure (it's the dns host name of our domain controller).
Using correct LDAP domain name - think so but not 100% sure (it's the domain name we all log into Active Directory under).
What's happening is, when I enter my AD user name and password on the LDAP Dashboard page and click Save, C5 says "Page Not Found".
If I try to run the Poll LDAP Users job from the automated jobs page, it just runs endlessly without really doing anything.
I'll keep digging into this and share what I find, but if anyone has any tips for troubleshooting this, I'd be grateful. Thanks!
[Update...] The Page Not Found thing was due to my having re-run my php install and forgotten to re-enable short tags support. This time, I just replaced all the short tags in ldap.php with the full <?php tags.
So now the poll job is running and now returning the following error message:
"No results returned. Check errors above.
Human: Only user accounts that don't have "Built-in" in thier description and don't have Mailbox or Email anywhere in their name."
[Update...] No results returned was caused by typo in the dc hostname. :-P It's now working. And by the way, in case anyone was wondering about whether it will run on 5.5, that's the version I'm running for this test.
Cheers, and thanks!
For example, our active directory user names are created in the typical <first_name>.<last_name> format. C5 does not normally allow periods in usernames. So whenever you edit a user account whose name is formatted this way (such as when adding the user to a group), C5 squawks about an invalid username, even though you can log on with such a username and be able to function normally just about everywhere else.
I think this is a pretty easy thing to fix - if nobody else gets to a fix before I do, I'll post one when I can get to it.
How will change passwords from C5 with this plugin?
I've been a fan of this addon ever since you posted about it and I've been continuously checking on your progress. The last version is really nice!
There's just a slight detail that I can't seem to understand: The "Group Import Prefix" seems to act as some kind of "filter" and not setting a "Group Import Prefix" prevents Groups from being set at all.
In my Active Directories, my groups have all names like "sggTeacher", "sggStudent" and I'm comfortable with using those names as my concrete5 group names. However, if I don't set a prefix at all, the groups won't even be considered. This is due to line 109 in "ldap_authenticator.php" that only adds the group if a prefix has been set.
In my case, that means using "sgg" as a prefix and setting up group names "Teacher", "Student" ...
The question is ... why? What's your reasoning behind such an approach.
I would suggest that you modify your PHP code slightly so that, if someone specifies a prefix, it gets removed from the group names but in case someone doesn't set a prefix, that it just considers the group names as they are. The could would then become:
Another minor detail that you might want to look into when you've got the time: the login markup and CSS has changed in concrete 5.5 (I think) so the new "ldap_login" page is looking all strange. You might want to use the new HTML markup from the new login page.
Thanks for the awesome work,
The problem is that concrete5 doesn't allow custom Login Controllers (without any hacks) that would allow to use ldap or other login methods. Any attempt to include another login method violates the marketplace rules and will definitely not make it in the marketplace at this time.
However, I have been able to successfully install, configure and run the aforementioned addon on my website. The addon in itself is stable but if you are not familiar with the concrete5 folder setup or not willing to dig into PHP code yourself, I wouldn't recommend installing it.
Although what I implemented for the proof-of-concept works fundamentally differently to your package, it was heavily inspired by your work.
The full details (and a copy of the code) is here:
It may soon be time for a complete reworking to fit in with c5's third party authentication standards referenced in the roadmap.
Anyways, thank you again!
I downloaded your attachment but I didn't find a readme file in the folder. Is there a set of instructions on how to implement the full ldap authentication? I have an ldap server available to use for credentials. I'm new to all of this so please be gentle.
If you're looking to implement LDAP authentication, download the ldap_auth.zip file and unzip it to the packages folder of your concrete5 installation directory. Log into your concrete5 website as an admin and click the "Install" link which shows up when you hover on the "Dashboard" in the top right of your site. You should see "LDAP Authentication" listed there - simply install it.
If you're looking to implement Kerberos Single Sign-On using Active Directory, simply follow the readme.txt that is in the single-signon.zip file on my other post.
Hope that helps :-)
Keith asked me to reply to you from here. The install was easy just as you
explained it but the ldap setup is now where I'm stuck. I've filled out
the LDAP Host Name/Address, Default Domain Name, and the Default Base
Query and haven't had any success logging in to the ldap server. I'm
assuming the Username and password is the one for the ldap server? I think
where my issue lies is within the criteria filter and group import prefix.
Have you had anybody setup this up successfully with a mac ldap server and
if yes do you have any examples or information on how to set this part up.
I really appreciate all the assistance you have provided.

I haven't had any experience with a mac LDAP server, although I doubt it would be all that different. A few things you could try:
- leave the criteria filter and group import prefix blank and test the connection (this will tell you if its this config that's the problem)
- check your LDAP server logs and make sure that your username/password is correct
- if all else fails, use the free LDAP Browser tool (http://www.ldapadministrator.com/download.htm) to verify your LDAP query
You might want to consider writing an official "How To".
Anyways, +1 for community support. :)
Thanks for the quick post. It's certaily appreciated.
It appears to be the config for some reason because I get invalid DN when I look in the LDAP logs. I've tried manipulating the various textboxes to see if I can get the correct configuration to the server, but I just can't seem to get there. Another intersting thing is when I leave the username field blank and click the save button, the username pops back into the field. Also, when I use the ldapsearch command on the server to test authentication/connection I have to use the -x for simple authentication. I didn't know if that would be helpful or not.
Is there a way I can show what's being posted to the server for authentication? I don't get much when I look at the logs. It just says invalid DN: email@example.com. I know the configuration information that I'm trying to use works, because I use the same information on another server appliance.
Any help would be greatly appreciated.
Is it giving you a specific error message?
A lot of the connection variable are not exposed; and assumptions are made. Check out the ~/models/ldap_authenticator.php file - specifically the "query" function.
Also, check out [url]http://phplens.com/lens/adodb/docs-adodb.htm[/url] for the documentation on how the ADODB connector works. (Search for LDAP on the page.)
Thanks again for a great module. It sure makes things easier than forcing my clients to remember even more passwords.
Hope that helps someone.
I have a question about your package.
I am trying it successfully but i notice that when you click logout you are calling index.php/login/logout instead of index.php/login_ldap/logout.
how can solve this? because I need to call logout function on login_ldap cause I have a custom logout.
thx in advance,
I am working on getting this set up and feel like I am missing something. Maybe it just can't be done.
If a user logs in what do I need to do to have that user auto join a user group.
Let me know if I am just missing something or this can't be done.
Prefix Setting: concrete5_
Group on AD: concrete5_Administrators
Group on you c5 site: Administrators
Does that make sense?
Specifying a group prefix and naming the groups correctly should do the trick however.
I have been playing around with this add-on and it has worked for me so far. I love it.
Where we have it installed now we have been informed that in the future we may need to first authenticate with a service. Does anyone know of a way we would be able to add in the ability to do this?
Any suggestions would be helpful.
As far as groups go, if I remember correctly, the only thing the package will do is put a c5 user into a c5 user group if the AD user is in an AD group with a given prefix to the same name as the c5 user group.
The main reason why I've kept this package in the forums and not put it in the marketplace is because it's never really a production ready package. It's more of a dev package that will hopefully get you running in the right direction.
It has worked well for the purposes that I used it for, but individual mileage will certainly vary. ;)
We too looked at nested groups, however it hasn't become a big enough issue for us to spend the time developing this feature. Based upon the small amount of research we did do, I definitely believe it's possible to get it work.
Thanks again for your work on this ijessup BTW :-)
We are still a ways away from 5.7, but I would highly recommend looking into the authentication system changes now.
5.7's authentication has been made much more modular, so hopefully LDAP will be able to be integrated a lot easier now and probably will be able to make things pretty robust.
One thing I add for those who use it:
Domain Administrators are no longer treated in a special way. Instead you have to create a group "<your_prefix>_Administrators" and add the persons that shall be admins inside of it.
I´m totally new in Linux so I´m sorry if I asked on some stupid questions.
I get as my school project to install concrete5 with LDAP.
I have installed concrete5 on our school debian server according instrucitons on this site
It works fine.
But I fail if I tried install LDAP. As I have read on this forum I downloaded ldap_auth.zip and ldap_authenticator.zip.
Then I put on my var/www/concrete5 directory and run unzip ldap_auth.zip command. When I look at dashboard --> install as admin I don´t see anything (as you can see in my attachment file)
at awaiting installation. So what I did wrong? I will be very grateful for any solution to my problem.
