Not necessarily. I have observed that session setups are not validated so
multiple auths on the same transport work ok. The treedisconnect and
logoffandx commands generate signing errors but that not a bug deal. With
preauth you dont get any signature errors and it is equivalent to a
workstation account so I advocate that as the proper solution. But I have
seen it work without.

I know, I was drawing a blank on this as well. NULL credentials do NOT
trigger signing and that is checked in our "crazy conditional" (now in new
isSignatureSetupRequired method). But the check for GUEST is commented
out. IIRC you claimed GUEST did not trigger signing but I later observed
that that was not the case so I commented out the exclusion. I'll just
have to enable guest on a machine and test it sometime.
