Here I am completly with you, not with the way to do it, but that we have a
valid point one should takle. The problem I see with the one password is: how
to deal with the password matching not all but only a few akas correctly.
Ignoring the session? Ignoring the akas not fitting to the password? The FTS is
only working on with a correctly password protected session or not. What's with
'partly' password protected sessions?
So I really like the idea of having an authentication per aka.
But when extending the protocol on this point I would recomend doing it in a
better downward compatible way.
What about introducing a new keyword, either as M_OPT MPWD <aka>
<password/CRAM> or as M_MPWD <aka> <password>? The old M_PWD would still be
used as with no password.
This would make a matching of password to aka fairly easy and a system could
easily support old and new style in paralell, like if there is no new password
line, I take a look in the old style protocol and if I see the new line I just
ignore the old style password.
I would think this way would make it much clearer for interpretation.
