I'm trying to publish LANDesk CSA gateway in a ISA 2006 server, and to publish it ISA server requires a SSL listener using a certificate to stablish the internal link with CSA. I don't know how to export the CSA certificate, Is there any procedure to export CSA certificates to be installed in the ISA 2006 server?
Your best option might be to configure a 3rd party certificate on the CSA and then use that certificate within the ISA 2006 Server. We have not tested this configuration, so this is something that you would have to test on your own. This document http://community.landesk.com/support/docs/DOC-24323 will walk you through how to add that certificate.
