Thread:Extension talk:LDAP Authentication/Problem to login for just a single user

Hello, I am at a loss because we have a single user (at least he is the only one I am aware of) that has problems to login to our Wiki. We still have a pretty old version of MediaWiki (1.6.6) running with LDAP Authentication Plugin version 1.1g and everything runs perfectly except for that one user. When I create debug output the last line for this user is "Binding as the proxyagentDN", for my user the next line is "Returned groups:cn=...". He already tried to login with his account at my PC but this did not change anything.

Does anybody have a clue what might be going on?
