Open BHOLD Self Service with account from other domain raises in access denied

I have configured FIM 2010 R2, so that users from another domain can access FIM Portal.

But, when I open BHOLD Self Service, I get an access denied error.

There is a one-way trust relation available between the domain in which FIM Portal resides and the foreign Active Directory domain. The ADMA works properly and in FIM Portal all users has been synchronized. Otherwise I was not able to logon with a user from the other domain.

Who can help me?

best regards, Koos Nienhuis
