autofs4 doesn't timeout cifs mounted shares

[Keith Allcock]

Binary package hint: autofs

Autofs is not auto unmounting after the timeout.

I have adopted using autofs on 3 machines, a 9.20 mythbuntu, and two 9.04 crunchbang machines.
On the crunchbang machines autofs will correctly honour the information in the auto.master and timeout the mounts when not in use ('not in use' is checked via lsof for the mount).
On the 9.10 mythbuntu box however the mounts always remain active although no files are in use. Manually unmounting works correctly.
Nothing in logged by autofs in messages/syslog
I removed any switches for the timeout to see if it was my config but even the default timeout time doesn't work.
(To see what timeout was relevant I run: 'ps -elf | grep autofs', you can see the timeout switch in the command)

The config and autofs versions on all machines are the same (4.1.4+debian-2.1ubuntu2).

My config files are attached.

Forgot to mention... there is lots of forum entries on this issue dating back a long time.
There is a debian bug for the previous version of autofs which was previous closed:

Thanks for the bug report. Can you see if you have the same problem with auotfs5?

I had tried autofs5 before to try and resolve without success.
This time I purged autofs first.

I kept the delivered version of auto.master and added my one line to it (the difference from my previous attempt was not to remove the +auto.master line).
Restarted and the mount umounted after the default 5 mins.

So yes, autofs5 works for me now!
