man mount.cifs - options:
Map user accesses to individual credentials when accessing the
server. By default, CIFS mounts only use a single set of user
credentials (the mount credentials) when accessing a share. With
this option, the client instead creates a new session with the
server using the user's credentials whenever a new user accesses
the mount. Further accesses by that user will also use those
credentials. Because the kernel cannot prompt for passwords,
multiuser mounts are limited to mounts using sec= options that
don't require passwords.
With this change, it's feasible for the server to handle permis‐
sions enforcement, so this option also implies noperm . Further‐
more, when unix extensions aren't in use and the administrator
has not overridden ownership using the uid= or gid= options,
ownership of files is presented as the current user accessing
