User Map File
If the administrator has chosen No Mapping, the first time an NT client
attaches to the NetStorage 6000, an entry is made in the user map file that
includes the client’s NT username, NT domain, NT RID, and an assigned
UID and UNIX username. The user map file entries have the following
format:
::::
To ensure uniqueness, the UID that is assigned is a number one greater than
any UID value found in the users.nis or users.map file. The assigned
username is the UID preceded by u. For instance, if the UID is 502, the
username is u502.
Group Map File
If the administrator has chosen No Mapping, the first time an NT client
attaches to the NetStorage 6000, the primary group for the NT client is
obtained and added to the group map file in addition to an assigned GID
and UNIX groupname. If the primary group for this client is already
present in the group map file, no changes are made. The group map file
entries have the following format:
::::
To ensure uniqueness, the GID that is assigned is a number one greater than
any GID value found in the group.nis or group map file. The assigned
groupname is the GID preceded by g. For instance, if the GID is 21, the
groupname is G21.
