 If, for example, the user id is 1000 then you can use the following...
+<code bash>
 uid=1000(user_name) gid=1000(user_name) groups=...
+</code>
-Make the following entry in your /etc/fstab file :
-//server_name/share_name /mount_path cifs defaults,uid=1000,gid=1000 0 0
+----
-Now when the share is mounted all files and folders will appear as the user with uid 1000. This is fine if you are the only user of the system. On a multiuser system this is problematic as other users will still be denied. Another option is to use dir_mode / file_mode to give everyone access:
+**__dir_mode / file_mode__**
-dir_mode=0777,file_mode=0666
+Setting the uid or gid is fine if you are the only user of the system.
