Accessing Files Created by UNIX Clients
When an NT user accesses a UNIX file, the UNIX file permissions are
translated into an ACL that then determines the permissions to grant. Recall
from HP NAS Server Security in a UNIX-only Environment that permissions
are granted to three distinct groups:
■
user
■
group
■
other
If the owner of the UNIX file does not map to a user in the NT domain, then
an NT user ID will be generated in the local UNIX domain. If the owner of the
UNIX file is recognized (or mapped) as a known NT user, then the
appropriate information will be exchanged so that the owner has the same
security privileges in NT that he or she had in UNIX. A similar process occurs
for the group identification and permissions. The Other field is mapped to the
NT Everyone account.
This table shows the mapping that takes place between the permissions.
Note
If share-level security is being used in the Windows
environment, then only the share passwords affect access. The
UNIX permissions have no effect.
