Roundcube installation with carddav / caldav / sabredav (DAV) / PHP
We are running our own mail server (hMailServer) and we are now deploying a webmail interface - Roundcube. In addition to the pure webmail UI, we wish to add shared calendars and contacts.
Our webmail currently runs on Windows Server 2008 R2 Enterprise Edition, IIS 7.5, PHP 5.4 installed, MySQL, hMailServer, Roundcube as webmail interface.
We are having some difficulties in installing and deploying the appropriate plugins for sharing, especially the SabreDAV software (in PHP) and the necessary carddav / caldav plugins (myroundcube.com), for which we seek help. Our webmail uses SSL (currently trial).
We also want to use SSL for DAV, IMAP and SMTP if possible.
A successful engagement would mean that we get either what we want or an answer that our solution is not possible and that an alternative is possible. No, we do not want to run Microsoft Exchange and yes, we must run the server with Windows Server 2008 R2.
I believe that what we want is a small challenge in itself but very possible.
Due to security reasons, the contractor must work on his or her own machine, delivering the final solution to us (instructions, copy of code, files etc.
