+ For mounts to servers which do support the CIFS Unix extensions,
+ such as a properly configured Samba server, the server provides
+ the uid, gid and mode so this parameter should not be
+ specified unless the server and client uid and gid
+ numbering differ. If the server and client are in the
+ same domain (e.g. running winbind or nss_ldap) and
+ the server supports the Unix Extensions then the uid
+ and gid can be retrieved from the server (and uid
+ and gid would not have to be specifed on the mount.
+ For servers which do not support the CIFS Unix
+ extensions, the default uid (and gid) returned on lookup
+ of existing files will be the uid (gid) of the person
+ who executed the mount (root, except when mount.cifs
+ is configured setuid for user mounts) unless the "uid="
+ (gid) mount option is specified. For the uid (gid) of newly
+ created files and directories, ie files created since
+ the last mount of the server share, the expected uid
+ (gid) is cached as long as the inode remains in
+ memory on the client. Also note that permission
+ checks (authorization checks) on accesses to a file occur
+ at the server, but there are cases in which an administrator
+ may want to restrict at the client as well. For those
+ servers which do not report a uid/gid owner
+ (such as Windows), permissions can also be checked at the
+ client, and a crude form of client side permission checking
+ can be enabled by specifying file_mode and dir_mode on
+ the client. Note that the mount.cifs helper must be
+ at version 1.10 or higher to support specifying the uid
+ (or gid) in non-numeric form.
