Changing Passwords with the plugin

[usafitz]

Hey all, I'm new to the forum, so first, I'd like to say hi and hello 

I've had some trouble configuring the password plugin.  Here's the log for after I tried to change my password on my roundcube site.

[15-May-2013 00:21:27 +0000]: DB Error: SQLSTATE[28000] [1045] Access denied for user 'user'@'localhost' (using password: YES) in /var/www/roundcubemail-0.9.0/program/lib/Roundcube/rcube_db.php on line 154 (POST /mail/?_task=settings&_action=plugin.password-save?_task=&_action=)

I think I narrowed it down to this setting in the config.inc.php file.  When I put in my root credentials, it was able to change my password... but that's obviously not the best way to do things.

$rcmail_config['password_db_dsn'] = "mysqli://MYSQL-USER:HASH-PASS-PHRASE@127.0.0.1/vmail";

What is the best way to configure this.  I am using virtual email accounts housed in a mysql database.  Which credentials should I be using in this setting and what type of hash is it using?  Where can I find this hash?  Any other information on how roundcube talks to the database would be appreciated if you have it.

thanks again for your help.  I look forward to hearing back from you.

The password can't be hashed, it has to be the actual password.

does the access have to be at the root level of mysql, or can I specifiy a database to access within mysql?

It should be a MySQL user with access to the accounts database, the less access to anything else the better.
