Consider the following scenario:

  • You use Microsoft SQL Server 2014 or 2012 Master Data Services (MDS) in an Active Directory domain.

  • An MDS administrator browses to the MDS website, and adds an Active Directory group or user to User and Group Permissions.

  • The group or user account that is added has the same name with a computer account within the Active Directory domain.

In this scenario, when the user tries to access the MDS website, an access denied error occurs.
