kvno X not found in keytab; ticket is likely out of date

[Laura Smith]

Maybe a couple of hours or so.

"klist -l" shows empty on a client I've tried.

When mounting, the client now shows :
mount.nfs4: access denied by server while mounting (null)
mount: mounting foo.example.com:/srv/share/foo on /mnt/foo failed: Invalid argument

Demsg on the client shows:
NFS: state manager: check lease failed on NFSv4 server foo.example.com with error 13

Rebooting the client has no effect.
