Thank you for taking the time to run such a trial test.

What do you think would be the best course of action following
 fsys main open -A ?
Delete all files owned by user and remove user from the FS user table?
Then perhaps recreate the user?
Or instead, just look around for what might be "amiss" (not sure where
to start)? (I'm not sure where the user information is searched for by
the system other than the user table -- what else could possibly affect
it?)

Regards
