Can you (or anyone who knows) explain this on more detail? The pointer to the 
page, specifically that section, doesn't really cut it. The way imap.conf 
comes with FC2T3 is:

sasl_pwcheck_method: saslauthd
sasl_mech_list: PLAIN

As we all know. Also, the file on /etc/sysconfig/saslauthd contains (among 
others):

MECH=shadow

With very little documentation about what was done on FC2T3, I created a 
password for imap admin user cyrus (listed on /etc/imapd.conf as "admins: 
cyrus"), --passwd cyrus--, su to it --su cyrus-- and after 'cyradm localhost', 
authenticating with the previously set password, I was ready to add users. Now 
those users had to be created on the system as regular users as well, just 
like cyrus is. And, of course, saslauthd must be running and so cyrus-imap.

The above procedures work. Proved. But, as some already noticed, the users 
created with cyradm must be also present on /etc/passwd and /etc/shadow and 
/etc/groups... in other words, they must be users of the system, even
'shell-less' one's, doesn't matter, they must be real users.

So, can you, or anyone, detail as simply as I just did, how to accomplish the 
userless (using /etc/sasldb or sasldb2) scenario?

Cheers,
