Unable to determine Kerberos encryption types supported by the kernel

[Bryce Harrington]

I've been noticing a lot of kerberos-related failures in the past
month's test runs.  (Specifically, the tests aren't producing any
results when run under KRB; they just report initialization failures.)

In the logs I spotted this:

Apr  5 01:22:56 nfs06 rpc.gssd[2917]: We will use this entry
(nfs/nfs06.nfsv4.pdx.osdl.net at NFSV4)

encryption types supported by the kernel; using defaults (1,3,2).

Have the encryption types changed for kernel configuration within the
last month?  There haven't been any configuration changes to kerberos
during this timeframe.
