EnableIT have developed a small php administration application for Zarafa version 6.30. You can download the latest version below:

Zarafa admin on SourceForge

Unzip in your web directory and browse to http://yourserver/zarafa-admin. Logging in as an administrator gives access to add/edit and delete users while logging in as a normal user allows password changes.
Please note this is only for Zarafa servers using the database back end.
