Hello, I read some posts about connecting OTRS to LDAP/AD on the backend for authentication. I haven't gotten this to work yet. System is CentOS5. What I have in Config.pm is: $Self->{'AuthModule'} = 'Kernel::System::Auth::LDAP'; $Self->{'AuthModule::LDAP::Host'} = 'mblauth01.mbl.edu'; $Self->{'AuthModule::LDAP::BaseDN'} = 'dc=mbl,dc=edu'; $Self->{'AuthModule::LDAP::UID'} = 'cn'; $Self->{'AuthModule::LDAP::SearchUserDN'} = 'uid=searchuser,ou=users,dc=mbl,dc=edu'; $Self->{'AuthModule::LDAP::SearchUserPw'} = 'secret'; $Self->{'AuthModule::LDAP::Params'} = { port => 389, timeout => 120, async => 0, version => 3, }; Apache error logs: [Thu Dec 20 15:28:49 2007] [error] [client 127.0.0.1] Global symbol "$Self" requires explicit package name at /opt/otrs/bin/cgi-bin/../../Kernel/Config.pm line 110.
