You should be able to see the mount using gvfs-mount. In Debian the
mount point from nautilus would be under /run/user/.
You don't say exactly what happens when you try a manual mount - unless
"nothing" is a full description, of course. If you looked on the server
you might find helpful logs.
(I'm assuming you have cifs-utils installed .)
Then "mount -v -t cifs //server/mount mountpoint -o user=nobody" should
work and provide useful information.
You could equally well put this in to .bashrc rather than in a
Template, or add an entry to /etc/fstab using the mechanism in
/rw/config/rc.local.
