Hi all,

On RHEL6 nfs-utils-1.2.3-36

man rpc.gssd says it -t wasn't specified then kernel gss contexts will be 
cached for the lifettime of the Kerberos service ticket used in its creation.  
Is there a way to see the contexts + service tickets in that cache?

Also, is there any way short of rebooting the client to evict one entry from 
that cache, or even clear the cache entirely?

(looking for this as I had situations where access was denied by the NFS 
server and I could see the principal was getting mapped to nfsnobody, etc. and 
was suspecting the account was changed on the KDC and the old context/ticket 
may have been causing problems)

Thanks,
Michael
