[xwiki-users] ldap-integration / Active Directory / sAMAcountName

Hello xwiki users, I have to integrate with an microsoft active directory server. The ldap-interface of xwiki (as in xwiki.cfg) works by default with the cn (the canonical name), i.e. "Pierre Dalluege". No one can really put his full name into the login name field, everyone wants to put the logon name, which is in this case "p.dalluege". This information is placed in the field "sAMAccountName". Other software packages require an account for "ldap log on and searches" and in the second step the look for the "sAMAccountName" and fill the field cn, email and others. Is there anyone to help? At least any ideas? Thanks a lot in advance, best regards Pierre
