I like to ask the same question, as it was still not answered /
validated by the other replies:

Is the information by David Collantes correct that cyrus-imapd coming
with FC2 can only be used with system user account for each mail user?

I hardly doubt that because it would be total nonsense to not compile
against sasl and to force such a setup. I think it is wrong and that
just the default setup uses saslauthd with MECH=shadow, like already on
FC1 this is the default setup for Sendmail's and Postfix's STMP AUTH. It
would make some sense and the (more experienced) user can decide to use
a different authentification mech / method for the mail account users
like an LDAP backend or instead of using saslauthd directly requesting a
sasldb2. As the upcoming cyrus-imapd package most widely is based on
Simon Matter's great packaging (he does a really good job since long
time), I assume being sticked to system user accounts is just wrong
information.
