Forum OpenACS Q&A: Re: How to use Active Directory credentials for logging into OpenACS
There are a lot of threads on this topic. Try searching the boards for more info but quickly, yes, you need auth-ldap and the aolserver module nsldap (the one that supports bind). You need to build nsldap, modify your config.tcl to set up the ldap pool and ensure that it's working by checking the log when your server boots up. Once you've got that working, you configure it by going to the Authentication section of the Control Panel. There, you will be able to add a new authority of type LDAP and configure the options for it using the "configure drivers for this authority" link.
About functionality, you can expect that if your users have email addresses in AD, they should be able to log in directly to your OpenACS instance (the local account will be created at login time). There is also work going into HEAD that will allow admins to search for users in an LDAP authority and add them to the local system.
Several of us are using the module successfully, against both AD and Novell's eDir. It's not an amazingly full featured integration (yet?) but it does work.
Let us know if you run into any issues while setting things up.
So far I have done following things with the server
1. Compiled & built aolserver module nsldap.
2. Modified config.tcl file as per the documentation (mentioned LDAP pool in the file).
3. In Package manager page, "LDAP authentication driver" shows 'Key' as "auth-ldap" (Are these pacakges one and the same? If yes, then I don't need to install auth-ldap separately.)
4. I tried to reinstall the LDAP auth. driver then server threw an exception as below:

How Can I enable the MergeUSer operation? or Is there any workaround for this?
Thanks
