Did you have any with this? I am evaluating using Concrete5 and need to be able to do this also.

Same needed here. A LDAP authentication schema would be greatly appreciated.

You could create a LdapHelper class in /helpers based on Zend Ldap stuff and add a single page to your dashboard where you handle your functionality.

Yeah, the single page approach would make the most sense. You'd essentially duplicate the login page and have a "login with ldap" page or whatever. In the controller for that page, you'd run your ldap queries and based on the results of that either log the user in or not.

I took this same approach building a google login package that used google's federated login api (variation of openID) to authenticate users off of a google hosted domain.

Before you go too far to develop the solution, someone else has already made some good progress on this. Please see the following thread:
