Thanks for the insight.

Basically this means that it is recommended to import the root certificate of 
the CA which Kolab uses for signing the certficates into the windows SSL CA 

IIRC this is best achieved when exporting the current public part of the CA 

	openssl x509 -in ca.pem -outform DER -out ca.der

and then offering it via 


and the mime-type 

	application/x-x509-ca-cert .

We then would advice the user to import the ca.der by clicking on the above 
URL from within IE.

I therefore propose that we add the above service offering the ca.der to Kolab 
HEAD and maybe Kolab 2.1.

In addition I think that other browsers on the windows platform like Firefox 
or Opera implement their own store for CA certificates which are of no use 
for Outlook freebusy purposes.

Is there any way to make sure that Toltec does not accept any self signed
