Login Failed Authentication Directory Server Configuration

[Mikael Winther]

We have changed the Directory Server Configuration to get LDAP information for logging in to HPSIM from another domain than the domain the HPSIM server resides in.
The connections test out OK (with the test connection button in HPSIM).
But the only login that works is still the login created on the HPSIM server,
The users and groups have been added to HPSIM with user: newdomain\username
group: newdomain\domain admins
HPSIM server has been restarted, to restart all services.
It is still only the old user account, from the old domain, that can login.

Is there anything i am doing wrong?
