Package: libpam-mount

Severity: important
Tags: upstream patch
Hi,
After migrating to squeeze I've been having difficulties with
libpam-mount. One of them is that it fails to detect the already mounted
cifs setups, so the cifs entries get mounted on each authentication.
Tracking the problem I found that the newer the mount.cifs adds a trailing /
to the device part in /etc/mtab and /proc/mounts. So, what use to be
//samba/share now becomes //samba/share/. Which makes the check made by
libpam-mount to fail.
So, I made a quick fix in libpam-mount, that removes the trailing slash
whenever its processing the mtab and mounts lines.
Which is something like this:
