Debugging Autofs problem
If you are having trouble automounting your file systems, want to check where the log that autofs being saved, it may be useful to run automount in the foreground.

Stop the autofs daemon

sudo service autofs stop
Run automount in the foreground with verbose information

sudo automount -f -v
From another terminal, try to mount your file-systems by changing directories into the mountpoint.
Check the output from the first terminal for clues as to why the mount failed or was not attempted.

 

Hope it help.
