Accessing Files Created by NT Clients

Directly mapping NT permissions to UNIX permissions causes some difficulty
because NT permissions have a greater level of complexity. UNIX users are
unable to use either the chmod or chown commands to modify the
permissions or owners of NT files. The table below shows which UNIX-to-NT
file permissions are mapped.

In addition to the permission mappings covered in the previous sections, the
following also applies:
If no ACLs are specified, then the UNIX permission will be rwxrwxrwx.
I
If the ACL is empty, then the UNIX permissions will be ---------.
I
If the only access allowed by the ACL grants full control to everyone, then
I
the UNIX permissions will be rwxrwxrwx.
In the absence of a group ACL, the owning group will be the user's
I
primary group and the group permissions are set to the same value as the
other permissions.
Additionally, if an NT file grants permission to the everyone group (and does
not specifically deny access to the owner or the group), then the same access
is given to the owner and the primary group. However, UNIX permissions
look for explicit permissions for the owner, group, and other. To allow the
same level of access in UNIX as NT, these files will have a permission of
r--r--r--.
