saslauthd and multiple mechs

[Mike Culbertson]

I'm aware that this has come up before 
(http://lists.andrew.cmu.edu/pipermail/cyrus-sasl/2007-September/001188.html) 
but (on Debian) the manpage for saslauthd states:

saslauthd supports one or more "authentication mechanisms"

so it's not entirely clear what the correct answer is.  Is there any way 
at all to use multiple auth mechs, aside from doing it through PAM?

TIA
