Thanks much! (for some reason I thought the only options available were
sasldb or pam for that setting)

However, I still get errors when trying to do PLAIN auth (haven't even
tried setting up SSL yet)

# imtest -u test1 -a test1 -w 1234 -v -m PLAIN 192.168.1.98
S: * OK mail.test Cyrus IMAP4 v2.1.11 server ready

AUTH=CRAM-MD5
S: C01 OK Completed

S: A01 NO no mechanism available

#tail /var/log/auth.log :

PLAIN [SASL(-4): no mechanism available: security flags do not match
required]

Also, could someone explain to me exactly what the difference between LOGIN
and PLAIN is? I haven't been able to see find any details in my RTFM'ing...

Can/will cyrus-imapd create a maildir (and INBOX) for a user that has
logged in for their first time?

thanks much!!
