ERR_SECURITY_MUS_USER_UNMATCHED: The DSS user is not configured to be matched onto a system user

When DSS impersonates a user, it must have a rule to determine the system user name which it is supposed to impersonate. This error means no rule has been configured for this user.


This issue can only be fixed by a DSS Administrator.

Select an impersonation matching rule in the administration panel for the faulty user. See User Isolation Concepts for more information about identity mapping.
