I've got an 'out-of-the-box' installation of VirtualMin on Ubuntu 10.4 and have installed the latest Roundcube (version .5.3) and all is working well except for the Change-password plugin. The form-page for changing the password shows up okay, but each time I attempt to change the password I get a message "Password could not be changed".
In the config.inc.php file I've set it to:
$rcmail_config['password_driver'] = 'virtualmin';
... as the default is 'sql' and the mail is not using MySQL.
There seems to be a few methods of getting it to work described in a number of blogs and sites, but they seem to be about earlier versions. I've worked through a number of them but no luck.
Has anyone got any hints on getting this plugin to work?
