Just getting a dev system set up for the first time.

Logging as the default admin user is fine. If I add a local user to the VCAC server, I can add that user to the Administrators group, and the login works.

If I add an AD user, VCAC correctly identifies the user in the DOMAIN\User format. But when I go to login as that user I get the following error:

Service Unreachable

A required service cannot be reached at the expected address.

Please contact your System Administrator for assistance.

Reference error REPO404.
