stale auxiliary GID on NFSv3 client allows files to be modified
Issue
- NFSv3 mount on the client with files read-writeable by a specific group.
- When the common GID is removed from a user and it should no longer should have read-write ability on a file/directory it had access to previously, that user is still able to modify the file.
Environment
- Red Hat Enterprise Linux (RHEL) 5, 6
- NFSv3 mount with group writeable directories.
- only local UID/GIDs are bring used from
/etc/passwd,/etc/group.
