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:
n
If no ACLs are specified, then the UNIX permission is rwxrwxrwx.
n
If the ACL is empty, then the UNIX permissions will be ---------.
n
If the only access allowed by the ACL grants full control to everyone,
then the UNIX permissions will be rwxrwxrwx.
n
In the absence of a group ACL, the owning group will be the user's
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--.
