This attribute specifies the name of a file service user map for TAS to use when converting externally-supplied user names into internal ones. If you set authent-proxy to on, TAS authenticates the external name and then converts it to its corresponding internal name; otherwise, TAS authenticates the internal name as usual. If you set client-encryption to on, TAS treats the internal name as a TAS user. Otherwise, TAS treats the internal name as a UNIX user.
If you do not define this attribute, TAS does not use a user map. This means that TAS assumes clients supply internal names--UNIX user names or TAS user names--for user names.
