Package: nfs-kernel-server
Version: 1:1.2.2-4
Severity: important

Hi, 

I observed the following after installing a Debian Squeeze network on
virtual machines:

After switching on sec=krb5 for the NFSv4 mounts, the mount process
hangs immeditely, it doesn't return at all:

root@workstation00:~# mount -t nfs4 -o sec=krb5 mainserver:/home0 /mnt

No error, nothing.  Ctrl-c brings you back to the command line.  The
same when logging in, as the automounter tries to mount the home
directory: After entering the password nothing happens.

I tried to find the reason and checked logs with rpc.gssd -fvvvv -rrr  
and rpc.svcgssd -fvvv, but could not find any indication there,
anything seems to work as expected.

I tried the kernel 2.6.38-bpo.2-686 from backports, same results.

Finally I installed the nfs-common and nfs-kernel-server from testing
on the nfs-server: 
ii  nfs-common         1:1.2.4-1
ii  nfs-kernel-server  1:1.2.4-1

And without further changes anything worked as expected.  Something
comparable (with some patch) is described here:
<URL:http://www.spinics.net/lists/linux-nfs/msg14723.html>, same
nfs-utils 1.2.2
 
It would be great if that could be fixed for squeeze.  If I can help
with more debug info, testing or full logs, please let me know.

Best regards,

     Andi
