Description Luc Lalonde 2011-04-29 17:24:43 UTC
Description of problem:

Here are our mount options (/etc/security/pam_mount.conf.xml):

<volume fstype="cifs" server="sambafileserver.foobar.com" user="*" path="%(USER)"
mountpoint="/usagers/%(USER)"
options="dir_mode=0700,file_mode=0600,serverino,nobrl" />

I've tested with the stock Rawhide version of 'pam_mount' and the latest version (2.10) that I compiled and installed on my test workstation.

Note:  Gnome3 that ships with Fedora 15 beta1 with the latest Rawhide updates works fine.

Version-Release number of selected component (if applicable):

kernel-PAE-2.6.38.3-18.fc15.i686
samba-3.5.8-68.fc15.1.i686
pam_mount-2.10-0.i686 or pam_mount-2.5-2.fc15

I'm wondering if it's linked to another CIFS bug that I've posted:

I should also mention that I've got no problems on Fedora 13 (KDE-4.5.5) with the same pam_mount options.

Network traffic dump

Here's a dump of the network traffic between the client and the Samba server using this command:

/usr/sbin/tcpdump -i em1 -s0 -w /tmp/cifs-traffic.pcap host samba-fileserver.foobar.ca and port 445

Comment 3 Luc Lalonde 2011-05-09 14:42:43 UTC
This bug is not related to bug id 700206 mentioned above...

I suspect a problem with GStreamer or Phonon.  Here are the errors that I get in my .xsessions-errors when I try to logout:

(knotify4:1996): GStreamer-CRITICAL **: gst_element_set_state: assertion `GST_IS_ELEMENT (element)' failed
WARNING: Phonon::createPath: Cannot connect  Phonon::MediaObject ( no objectName ) to  Phonon::AudioOutput ( no objectName ).

Comment 4 Luc Lalonde 2011-05-27 20:09:57 UTC
I'm closing this ticket... the problem is no longer there applying latest Fedora 15 updates.
