I recently moved the root master server for NIS+ to a new machine and set up
automounting for home directories and a number of software packages.
Since then there have been large numbers (100s/day) of messages appearing in
the /var/adm/messages logfile on the root master server such as:
Aug 23 16:20:45 tulip nisd: _svcauth_des: corrupted window . . .
Aug 23 16:56:20 tulip nisd: _svcauth_des: timestamp is earlier than . . .
Aug 23 17:01:15 tulip nisd: _svcauth_des: invalid timestamp received . . .
And occasionally on various clients (which supply automount directories):
Aug 23 14:45:39 king mountd: authdes_validate: verifier mismatch
Things seem to be working more or less except that the automounter core dumps
occasionally, and intermittently logins and file system commands slow to a
crawl and some automounts fail. Unfortunately all the manuals I have here
seem to be kind of short on trouble shooting info.
The 100s of timestamp messages are harmless according to Sun.

The authdes_validate messages seem to be caused by NIS clients (which did
NOT have credentials) providing automounted filesystems to the NIS+ machine.
If all your machines do have credentials, you might try to rebuild them.
This seemed to clean up most of the messages, I'm still tracking down a
couple of occasional /net mounts of far flung clients.

The corrupt window messages look like a credentials problem. It was suggested
that an nisupdkeys on the master nis+ server followed by nisping org_dir
might fix the problem. Since I was already going to rebuild the clients, I
re-entered the credentials to be safe and let the rebuild handle things.
All the corrupt windows messages disappeared.

The automounter dumps seems to have stopped for the time being although login
responses are still flakey sometimes. No idea if there is a connection.
