Sendmail/Dovecot Login Authentication With Cyrus-Sasl v2?

[Ciba LO]

Hello,

The default FC4 smtp/pop3 login authentication (sendmail auth login and
dovecot login = pop3) will check userid/password against the password
file located at /etc/passwd.  I am just wondering if it is possible to
modify the configuration parameters such that the login authentication
can check userid/password against the password file, /etc/sasldb2,
created via saslpasswd2(cyrus-sasl v2).

I have just made a fresh installation of FC4 with package group
selection of everything.  My Sendmail/Dovecot configuration parameters
are modified from the defaults as follows.
/etc/mail/sendmail.mc
define(`confLOG_LEVEL', `15')dnl
define(`confAUTH_OPTIONS', `A')dnl
TRUST_AUTH_MECH(`LOGIN PLAIN')dnl
define(`confAUTH_MECHANISMS', `LOGIN PLAIN')dnl
dnl DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl
dnl FEATURE(`accept_unresolvable_domains')dnl

/etc/dovecot.conf
protocols = pop3
login = pop3
login_executable = /usr/libexec/dovecot/pop3-login
pop3_executable = /usr/libexec/dovecot/pop3

Thank you in advance.
