I am trying to make Zimbra available to remote users through
a Cisco 3005 VPN concentrator. This device authenticates remote
users with an RSA token, then provides an https session to itself
as a proxy for select internal web resources.
When trying to use Zimbra through the concentrator, the Zimbra
icon and url display, and the browser fills with the sand-colored
background, but that is as far as I get.
