--- Comment #6 from Rick Macklem <rmacklem@FreeBSD.org> ---
Not exactly. sec=krb5 says that a RPCSEC_GSS (think Kerberos) session
is used to identify the user for all RPCs. The difference w.r.t. krb5p is that
it does not encrypt the NFS payload.

I doubt it will make any difference, but it sounds like you'll know soon
enough.

I now have a hunch w.r.t. what might be broken, but I need to look at the code
(and if my hunch seems correct) and maybe come up with a patch.

You could try the "syskrb5" mount option, which avoids use of the keytab and
allows "system operations that maintain the state" to use AUTH_SYS, while the
rest (all involving file data) use Kerberos.
(If my hunch is correct, this will not fix the problem, but might
cause it to behave
 better.)
