When I upgraded to Ubuntu 14.04 it also upgraded cifs. In Ubuntu 12.x a network mount script I had would nicely mount a Windows network share as read/write. My attempts at updating it to work with the new cifs have failed, see syntax attempted below which results in a read-only mount for my non-root account. Note that even after making mount path 777/user:user the following results in the mount path changing to 755/root:root.
sudo /sbin/mount.cifs $SHAREPOINT $MOUNTPOINT -o username=$user dom=$domain forceuid=$user forcegid=$user dynperm file_mode=777 dir_mode=777
