Re: [xwiki-devs] Problem connecting Xwiki with OpenLDAP

I have configured Xwiki (release 1.6-milestone-2.12601) to authenticate against my OpenLDAP (v2.3.35). I am continuously getting a "Wrong user name" message on my UI. On investigating my ldap logs, I found that Xwiki first authenticates successfully to OpenLDAP with the users id & password. However it then tries to do a lookup of the user (I assume for the details of the user), and at that time, it does not seem to be passing the base DN in the request. In such scenarios OpenLDAP returns a "No such object" error. I tried to do a test using ldapsearch without passing the base, and I got the same error. Also, the error did not occur when I passed the base parameter to ldapsearch. I am trying to trace through this problem in the source, but meanwhile, would like some help in figuring out whether my configuration is wrong, or if someone has encountered a similar problem before.
