There is no need to modify any code;  SASL can already do this.  A user
can have multiple passwords, so if one of those matches your global
password.

If your Cyrus install supports saslauthd for PLAIN/LOGIN authentication
and saslauthd is using PAM you can add the pam_allow [which always
succeeds] or some other module, PAM modules stack and one can be marked
as 'sufficient'.
