trusting multiple auth servers in the 9grid

	the problem we're trying to solve is: how do we boot a file server
	that trusts users from two authentication domains.  for example i want
	to have my own set of university of calgary users, which do not
	necessarily need to know about 9grid, but i also would like to allow
	users known to the 9grid auth server(s) to come and play on my
	network.

If you're using a fossil file server, that shouldn't be a problem.

1) The factotum on the machine it runs on needs to have p9sk1 accounts/passwords
in both domains

2) It should (if you want to do anything else) also have in its /lib/ndb/local

auth=<auth server for first domain> authdom=<name of first domain>
auth=<auth server for second domain> authdom=<name of second domain>

If this doesn't work, tell me and I'll fix it.  Factotum is supposed to allow
this though I haven't tried it since rsc's last rewrite.
