I'm trying to integrate an old Development Tridion 2009 with an OpenLdap I installed in the same machine. I achieved to configure the Directory Service, ISAPI Filter and impersonation User in the Tridion. Also configured this impersonation user in the app pool of Content manager, in IIS.
I have added correctly some dummy users from the test openLDAP in the content manager. The problem is that when I try to log in Tridion with those users added, there appears an authentication problem, like the Ldap user does not exist.
What could be the problem with the log of those Ldap users? Why is there the error: "unable to bind with admin user" in the Log?
NOTE: The group sync in directory service is disabled, I'm adding manually the users in Tridion.
Following Dominic tips I tried to connect using Ms LDP.exe to test the filter credentials. Making a simple bind seems to work. What kind of bind makes the tridion ISAPI filter?
