======================
To permit users to ummount directories that they have user mounted (see above),
the utility umount.cifs may be used. It may be invoked directly, or if
-umount.cifs is placed in /sbin, umount -i can invoke the cifs umount helper
+umount.cifs is placed in /sbin, umount can invoke the cifs umount helper
(at least for most versions of the umount utility) for umount of cifs
-mounts. As with mount.cifs, to enable user unmounts umount.cifs must be marked
-as suid (e.g. "chmod +s /sbin/umount.cifs"). For this utility to succeed

-match the uid of the user who mounted the resource.

Also note that the customary way of allowing user mounts and unmounts is
(instead of using mount.cifs and unmount.cifs as suid) to add a line

Unicode on the wire.

The mount.cifs mount helper also accepts a few mount options before -o
