Use Group ID Permissions

Specifies security checking for Windows clients of files with UNIX security when the person requesting access is not the file owner. In all cases, Windows NT client requests are checked against the share-level ACL (Access Control List). Then, if the person requesting access is the owner, the "user" permissions determine the access.

In this case, if the person requesting access is a member of the file’s owning group, the "group" permissions are used; otherwise, the "other" permissions are used.

In this case, the desired access of the person requesting access is checked against the file’s "group" permissions, and the "other" permissions are ignored. In effect, the "group" permissions are used as if the Windows client were always a member of the file’s owning group, and the "other" permissions are never used.

If you do not plan to use share-level ACLs to control access to UNIX security style files (that is, in a UNIX qtree), you might select Yes.

The default value for this field is Yes.
