Instructions
The automatic user mapping process maps together the Unix UID and Windows SID. This is done by matching the user name from the UDS to the user name from the AD. A Unix user does not have to map to a corresponding Windows user when using NFS to access a file system configured with a Unix or native access policy.
The system automatically maps a Windows user to a Unix user when the same user name is defined to the Unix Directory Service (UDS) and Windows Active Directory (AD) where Internal user mapper is used when you use CIFS (SMB) file shares, but an External user mapper is used when you use multiprotocol file shares .
In Unity Replication, in replicating a NAS server,the usermapping info is replicated to the target as tested in the lab enviroment.
