I'd suggest looking into PAM authentication. I've got my whole system
authenticating to an LDAP database. If I remember correctly (I'm not at
home so I can't look this up on my computer), you can run authconfig and
select SASL as one of the authentication methods. I think Dovecot
authenticates through PAM by default, so it should be ready to go if you
do that.
