[dev] Auth fails trying to SetPassword to LDAP

Hi all, I've made some changes in Kernel::System::Auth::LDAP: I've added known Active Directory errors and patterns to recognize them. Then, when an Agent tries to log in and fails, OTRS will show why it failed (e.g.: password expired or lock). But when I'm trying to run UnitTests for Auth, it fails because it tries to run SetPassword to my User LDAP Backend, and I can't figure why it uses my Config.pm config instead of the ConfigObject->Set at the start of the Unit. I'm no expert in Unit Testing and I don't really know what to do now. What would you do? Kind regards, Juan Clavero
