This is the first draft of the kolab-server. The web interface should work,
namely adding/removing/modifying users, and the LDAP authentication should
work with Apache, PHP and cyrus-imap. There's still some work to do,
specially testing postfix and proftpd.

To test it, do the following:
1) /sbin/kolab_bootstrap -b (note the manager password)
2) service kolab start
3) point your browser to https://localhost/kolab/admin and login as
   user "manager", with the password chosen in step 1.
4) create users
5) point your mail client smtp and imap servers to localhost, and try to
send yourself some mail, and read it.

To test the calendaring functions, you'll need the kroupware client, or
Microsoft Outlook with the Binary connector (proprietary).
