Hi !!!! I have a Zimbra Server, I´m using it's LDAP server (customized OpenLDAP) to authenticate my OTRS installation. I can authenticate from the agents configuration, but I can't from the customers interface. My configuration options: $Self->{'Customer::AuthModule'} = 'Kernel::System::CustomerAuth::LDAP'; $Self->{'Customer::AuthModule::LDAP::Host'} = 'mail.COMPANY.net'; $Self->{'Customer::AuthModule::LDAP::BaseDN'} = 'ou=people,dc=COMPANY,dc=net'; $Self->{'Customer::AuthModule::LDAP::UID'} = 'uid'; $Self->{'Customer::AuthModule::LDAP::AlwaysFilter'} = '(&(objectclass=zimbraAccount)(zimbraMailStatus=enabled))'; $Self->{'AuthModule'} = 'Kernel::System::Auth::LDAP'; $Self->{'AuthModule::LDAP::Host'} = 'mail.COMPANY.net'; $Self->{'AuthModule::LDAP::BaseDN'} = 'ou=people,dc=COMPANY,dc=net'; $Self->{'AuthModule::LDAP::UID'} = 'uid'; $Self->{'AuthModule::LDAP::AlwaysFilter'} = '(&(objectclass=zimbraAccount)(zimbraMailStatus=enabled))';
