I'm attempting to setup a RSA authentication manager with a Microsoft Active Directory as the identity source. When I try to login from the Windows login client the login attempt failed and I recieve the message Unable to resolve principal by login ID and/or alias in the authentication monitor.

I am under the understanding that this error message is occuring because Authentication Manager cannot resolve the username CONTOSO\Operator to the username Operator.

Any suggestions how to resolve the problems mapping the active directory users to the Authentication Manager database? Is there a global alias mask like CONTOSO\*?

In the RSA Authentication Client, there is an option to "include domain with login". It was checked. It should not have been.
