I’m setting up a RoundCube instance for one of my domains, and I would like to add the password plugin (http://trac.roundcube.net/browser/trunk/plugins/password). It supports several different protocols for changing passwords, but I don’t see an obvious reference for how InterWorx handles this. Can anyone provide assistance?
No, this is a custom install due to the level of customization and branding required by the user.
Probably you have to use ‘vpopmaild’ as the password driver as iworx uses vpopmail.
222 // vpopmaild Driver options
223 // -----------------------
224 // The host which changes the password
225 $rcmail_config['password_vpopmaild_host'] = 'localhost';
226
227 // TCP port used for vpopmaild connections
228 $rcmail_config['password_vpopmaild_port'] = 89;
I have had success with cpanel driver on a cpanel shared host (of course, the built-in cpanel.php file didn’t work; I had to replace it with one downloaded from roundcube forum, the latter also doesn’t require cpanel username & password to be entered in the config file, they are not needed.
231 // cPanel Driver options
232 // --------------------------
233 // The cPanel Host name
234 $rcmail_config['password_cpanel_host'] = 'server.myhost.tld';
235
236 // The cPanel admin username
237 $rcmail_config['password_cpanel_username'] = 'I didn't give this';
238
239 // The cPanel admin password
240 $rcmail_config['password_cpanel_password'] = 'Say no for this too :) ';
241
242 // The cPanel port to use
243 $rcmail_config['password_cpanel_port'] = 2096;//webmail port (nonssl 2095)
244
245 // Using ssl for cPanel connections?
246 $rcmail_config['password_cpanel_ssl'] = true; // my host uses ssl
247
248 // The cPanel theme in use
249 $rcmail_config['password_cpanel_theme'] = 'rvskin'; // my host uses rvskin
Really? As far as I can tell vpopmaild isn’t running on my system…
I am not sure about the daemon name (i.e it may not be called as vpopmaild) but what I know (up to my knowledge) is IWorx uses vpopmail (as I remember iworx crew suggesting to use vdeldomain for the domain’s mail to be taken care of elsewhere, i.e no mail accounts on the iworx server; so iworx uses vpopmail, but not sure of its daemon’s name)
IWorx-Paul said “we’ve provided a password plugin for roundcube for quite a while now” on thread http://forums.interworx.com/showthread.php?t=3340
He knows more about it, but speaks on the forums very rarely these days ( I guess 
).
Have you tried setting “vpopmaild” as the driver in roundcube config?
PS: if you have your license directly from iworx people, I think you may open a support ticket regarding the roundcube password plugin.
I have tried the vpopmaild driver, but it returns a failure. I will open a ticket and see if they can provide assistance.
