kolab and existing Apache on Red Hat?

[Mark Johnston]

I'd like to try Kolab on a box that already has Red Hat Enterprise Linux 
  installed.  That means the www root is at /var/www/html/.  But kolab 
installs its admin interface under /kolab/var/kolab/www/.

Any suggestions on the best way to have kolab and the existing Apache 
installation work together?  Or must I give up using the box for other 
Web services if I want to use it as a kolab server?

Looking forward to trying it out.

Thanks,

Mark J.
