I'm using automount (Linux kernel based automounter) to access shares on a NFS server. Usually, automount mounts the shares only when they are accessed, and also dismounts the shares if they have not been accessed for a certain time. This does not work as soon as a KDE session is online:

Sooner or later, all shares (mounted under /net/nfsserver/share/) are automatically mounted, however, there has been no access to the driver by the user yet. Moreover, the shares are never unmounted, even if there is no user activity at all.

Unmounting the shares manually (umount /net/nfsserver/share/) works without any problem, however, the share is automounted again at once.

I cannot find out any process accessing the shares, which would explain autofs' behaviour. However, everything works as expected as long as no KDE user is logged in: Shares are not automounted, and if they where automounted by some user, they automatically unmount after this user has logged out. So there must be some KDE process accessing the shares and hindering automount from doing its job.


Reproducible: Always

Steps to Reproduce:
1. Set up NFS shares with automount (standard procedure)
2. Start a KDE user session
3. Try to get rid of the automounts

Actual Results:  
Auomounts are active all the time, unmounted automounts (by shell command) get remounted at once.

Expected Results:  
Automounts should only mount when accessed by the user and unmounted after the specified time out.
