Morning!

I think the issue is with the 1 you added. It has to be just after the AuthModule but not after the ::

Let me explain: The LDAP modules expects some parameters: Host, BaseDN, etc. These names cannot change. What can change is the identifier of the auth module you're configuring. I think it should be something as:

$Self->{'AuthModule'} = 'Kernel::System::Auth::LDAP';

$Self->{'AuthModule::LDAP::Host'} = '10.0.0.2';

$Self->{'AuthModule::LDAP::BaseDN'} = 'DC=DOMAIN01,DC=local';

[...]

$Self->{'AuthModule1'} = 'Kernel::System::Auth::LDAP';

$Self->{'AuthModule1::LDAP::Host'} = '192.168.0.2';

$Self->{'AuthModule1::LDAP::BaseDN'} = 'DC=DOMAIN02,DC=local';

[...]

Best,

Juanma

Greetings,

I'm setting up an OTRS 6 installation on CentOS 7, with the latest version of OTRS (installed today). OS is fully updated.

Following the documentation at https://doc.otrs.com/doc/manual/admin/6.0/en/html/external-backends.html#agent-auth-backend-ldap I was able to configure OTRS to authenticate and successfully log in on the primary domain that I want to use (Windows AD back ends).

I added a second domain by adding "1" to the end of the AuthModule and AuthSyncModule clauses, but I'm getting an error when trying to log in with a user on that domain stating "Authentication succeeded, but no user data record is found in the database." In /var/log/messages the error is OTRS-CGI-99[14435]: [Error][Kernel::System::User::UserLookup][Line:969]: No UserID found for 'username'!

I suspect (hope) there's just some silly configuration error I'm not seeing.
