Bug description:
This bug can cause an installation's filesystem to fill up due to excessive logging by rpc.gssd, when the user's Kerberos credentials have expired and they have /home mounted via Kerberised NFS.

An explanation of how the bug has been addressed in the development branch, including the relevant version numbers of packages modified in order to implement the fix.

This bug has been fixed in the development branch, by way of a patch (fixed in 1:1.1.2-4ubuntu2)

The patch is attached to this bug report.

TEST CASE: have a system that mounts /home via Kerberised NFS. kdestroy. Wait ~15 minutes for rpc.gssd's cached credentials to expire. Perform activities that attempt to access files in $HOME. Much logging like what is below will occur.

This is a very simple patch. The potential for regression is slim, as all this patch does is decrease the logging verbosity of a few messages below that of normal operation.
