sets the uid that will own all files or directories on the mounted
filesystem when the server does not provide ownership information.
It may be specified as either a username or a numeric uid. When not
specified, the default is uid 0. The mount.cifs helper must be at
version 1.10 or higher to support specifying the uid in non-numeric
form. See the section on FILE AND DIRECTORY OWNERSHIP AND
PERMISSIONS below for more information.
if you want to force the uid to an expected one, use uid. The same applies to groups (gid).
$ mount -t cifs //10.151.170.170/events /var/blarg/copy-to -o blarg,password -o uid=1000,gid=100
To find uid and gid, you can use
$ getent passwd <username>
where first 1000 is uid and 1005 gid (values change, not order).
