Hi, I've spent the entire day going through docs and websites on getting OTRS authenticating to Windows AD via LDAP and am close, but still get a problem: [Thu Nov 22 19:04:49 2007] [error] [client xx.xx.xx.xx] Message: Search failed! base='CN=otrs_ldap_allow_A,OU=Groups,OU=Builtin,DC=<ourname>,DC= local', filter='(member=CN=Michael Mansour,OU=CT_Users,OU=Users,OU=<ourOU>,DC=<ourname>,DC=local)', Success, referer: http://xxx.xxxxx.local/otrs/index.pl The tutorial I also followed was here: http://trinityhome.org/Home/index.php?wpid=98&front_id=18 which details how to use the LDAP to sync to the DB, but I have tried just AD authentication with the same "Search failed!" error. I can provide more details but does anyone know what the "Search failed!" error means or how I can resolve it? Also, what would be the typical "ldapsearch" command I could use to duplicate the entries in the config.pm file? Thanks. Michael.
