Requester access denied

Followed the instruction on Data Owner and added an employee as requester, however the user can't login to Web portal.

When login using "Login as current Windows User" we get: "Invalid access code" error.

When login by manually type in username/password/domain. we get: "Access denied. You do not have the access right to one or more ARM features. Please contact your ARM Server administrator if you need that right."

For testing. If I create a role manually in role manager and give the user "Auditor" role, he can then login.
