NFSv4: Listing of files hangs

[Johan Marcusson]

I've just configured NFSv4 with kerberos between two machines, and
things are finally starting to work. There is however one problem,
listing of files hangs. I can create and edit files on the server, and
they get the right owners etc. But if I do ls on the remote directory
from the client, it just hangs forever. This includes trying to do
tab-completion.

When I first mount the directory, I get this from rpc.gssd -vvvf on the
client:
...
DEBUG: serialize_krb5_ctx: lucid version!
...

Other than that, nothing strange shows up in any logs.
I run nfs-utils 1.0.12 and kernel 2.6.19 on both client and server.
If I forgot any important details, please tell me. I would be really
greatful if anyone colud help me with this! :-)
