/**
* SASL Password Driver
*
* Driver that adds functionality to change the users Cyrus/SASL password.
* The code is derived from the Squirrelmail "Change SASL Password" Plugin
* by Galen Johnson.
*
* It only works with saslpasswd2 on the same host where Roundcube runs
* and requires shell access and gcc in order to compile the binary.
*
* For installation instructions please read the README file.
*
* @version 2.0
