[sork] Using passwd with a cyrus sasldb setup

[imp]

Hello,

  I have a mail server setup with cyrus imapd and virtual users via
  sasl. So far, I've got forwards and vacation pointed to ingo in
  registry.php, but I would like to get the passwd module working for my
  users.

  How do I configure the passwd module to call
  /usr/local/sbin/saslpasswd2 -p to change a user password? My initial
  thought was to setup a sudo(8) command calling saslpasswd2 to do this.
  Perhaps by modifying the example expect script? Has anyone done this
  already?

  Please advise if you think I'm going about this the wrong way, or if
  there's a much easier way to do this.

  Thanks.
