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.
