Which version of SASL? You definitely want 2.1.17.

Just read the docs on how to configure the SQL auxprop plugin. Then in
your imapd.conf file, you'll have options like the following:
sasl_mech_list: PLAIN LOGIN
sasl_pwcheck_method: auxprop saslauthd
And you'll need to run:
saslauthd -a shadow
This config will limit the server to plaintext authentication which will
happen against /etc/shadow and then the password will be inserted into
mysql. The next time the user authenticates, the password will be
pulled from mysql (given the order of pwcheck_method).
Once all of your users have authenticated at least once, you can remove
the mech_list option or add other mechs to the list.
