Active Directory Domain Services(R) contains multiple users which match attribute <%1>.  Only one Windows(R) user should be assoicated with each sAMAccountName.

 With multiple Windows users associated with one sAMAccountName, Server for NFS cannot determine which Windows user is requesting access to files.  No Windows users associated with the same sAMAccountName will be able to access files through Server for NFS.

 Try removing the duplicate sAMAccountName entries.
