Fixed and updated on sources.  Login wasn't rforking the name space so
that the second time, you were connected to your own factotum as alice.

No, I'm running auth/kfs server as name 'venus'
which responds to 'bootes' for many users, and has different user ID
from 'okamoto' running terminal, and is that hostowner.

You run as hostowner on the auth/kfs system, no?

I meant if user id is the only reason of that problem, why we see difference
between real full syatem and Auth/kfs system...

well the only thing different there is the file server, so possibly in
the way it speaks with factotum vs the way kfs speaks to factotum. just
a guess though.

I have same problem when I use auth/login at our full system,
however, I don't have no problem when I use the same command
in my home two PCs system (Auth/kfs + terminals).  I wonder what
is the difference between these two cases.

Factotum sort of broke login.

When you run login, your process becomes owned by the new id.
However, unless the factotum you are using is owned by a userid
that can 'speak for' other uid's, your new process can't authenticate
to any resources off of your machine.

One way around this is to run factotum as the new user and they
rebuild your name space.  I need to think about this.

In trying this out, I think I found an authentication bug also...

im having trouble getting this command to work the way i think its
supposed to.  in the man page it says that it allows you to change
your authenticated id. So if im understanding this right, if I booted
up as user A, and need to quickly do something as user B, i can type
auth/login B, enter the password, and do things as user B from within
that namespace. However when I do this, I have no permissions anywhere,
even to /usr/B/

i guess am i just totally missing the point of that command? or is
something misconfigured?

thanks
Andrew

misc background:
my plan 9 network has an auth server, cpu server, file server and diskless
terminal. This exchange occured on the terminal.
