Sets the Auth Unique Name for the user. The Auth Unique Name is used with users that are synchronized from an external authentication source, and represents the user's unique name within that authentication source, as opposed to Login Name, which uniquely identifies a user within Plumtree). Note that setting this is illegal for users whose passwords are stored in the portal database (ie, has a Plumtree AuthSourceID).
