dovecot - Jun 2008 - Using sork-passwd from Horde to change dovecot password

I'm using in my server dovecot and Horde to provide IMAP and Webmail 
for virtual users. Their password are stored in a passwd file, since the 
setup is quite simple and small. I'd like to use the Horde module 
sork-passwd to allow changing of the passwords. Apparently, this can be 
done for the case of passwd file by using an expect script, or simply 
calling a program that receives the data.

    It should not be hard to write a Perl (or Python, or whatever) 
script that does that. I'm just asking if someone has already done that 
and is willing to share the solution.

OK, since apparently nobody needed that before, here's a quick and dirty
solution. There is lots of room for improvement, but it Works For Me
(and My Setup). First, this goes in the passwd's backends.php:

$backends['dovecotpasswdfile'] = array(
    'name' => 'localhost',
    'password policy' => array(),
    'driver' => 'procopen',
    'params' => array(
        'program' => '/usr/local/bin/chdovecotpw'
    )
);

The script is attached. A big problem is that I had to pass the password
in the command-line, because dovecotpw seems to play tricks in order to
read the input, simply writing the password twice to its STDIN does not
seem to work.
