Trying to set otrs so users from child domain can open tickets. By changing the Active Directory port from 389 to 3268 (global catalog port) and changing auth:uid to "userPrincipalName" , I can get users from the child domain to authenticate using "username@childdomain.parentdomain.com" at the login page. The user authenticates but otrs cant find/create a record for them with the following error:

Authentication succeeded, but no customer record is found in the customer backend. Please contact your administrator.


Apr  2 11:09:56 otrs OTRS-CGI-10[7503]: [Notice][Kernel::System::CustomerAuth::LDAP::Auth] CustomerUser: administrator@childdomain.parentdomain.com (CN=Administrator,CN=Users,DC=childdomain,DC=parentdomain,DC=com) authentication ok (REMOTE_ADDR: 10.10.10.6).
Apr  2 11:09:56 otrs OTRS-CGI-10[7503]: [Error][Kernel::System::CustomerUser::SetPreferences][Line:504]: No such user 'administrator@childdomain.parentdomain.com'!


Is this because otrs cant find the user under the baseDN?

current baseDN:  dc=parentdomain,dc=com

is it posible to specify multiple baseDN like:

baseDN= dc=parentdomain,dc=com;dc=childdomain,dc=parentdomain,dc=com



How can I get users from the child domain to be able to use otrs to open tickets?
