Using native apache with kolab

[Alex Potter]

Currently, I have 2 instances of apache running on the machine that acts as my 
general-purpose server. (ubuntu-8.0.4). 

My kolab installation was build from the openpkg sources and the kolab 
instance of apache is configured to listen on a non-standard port for HTTP, but 
still uses 443 for HTTPS, so as not to interfere with pre-existing uses of 
apache. 

Is there something odd about kolab's default apache configuration, or would it 
be relatively easy to import the kolab-specific configuration into the other 
instance?

TIA
