I followed this step-by-step guide [1], but it doesn't work.

The error messages in /var/log/auth.log look quite familiar to me:

pam_mount(mount.c:72): mount error(101): Network is unreachable
pam_mount(mount.c:72): Refer to the mount.cifs(8) manual page (e.g. man
mount.cifs)
pam_mount(pam_mount.c:521): mount of ben failed

---------------------------------

In my experience the switch to udev or some other parallel booting
process (not sure what did it) in more recent linux distros has caused
the init sequence to be violated.  So no longer can you count on S1
being finished before S99 starts.  I have had to do one of two things to
resolve this

RHEL: all mounting commands are put into /etc/rc.d/rc.local, because
that file is explicitely called after all other startup scripts have
completed.  (although on Fedora 14 this doesn't even seem to be the case
anymore...?)

SLES: Create a startup script that waits for your network interface to
come up before executing mounting commands.  Here's a simple, non-robust
one (where "do_network_mounts" actually does the mounting commands):

#!/bin/bash

# wait for a network interface to come up if we're running scripts in
parallel mode
while [ `ifconfig | grep 192.168 | wc -l` -eq 0 ]; do
  sleep 5
done

/mnt/do_network_mounts
