We have a Cisco ASA in front of our Exchange 2010 OWA application. We needed to create a “bookmark” to point to OWA. Since we are using Forms based authentication, we did not want users to have to re-login after just logging into the ASA. I found this link on how to setup the Bookmark for SSO and Exchange 2010 OWA. We wanted to take it a step further and force the “Light version” of OWA until we could upgrade the ASA code (we are using an older rev and OWA JavaScript is not working correctly). To do this you need to change the “flags” post value to “1”.
So, to “Force the Light Version of Exchange 2010 OWA on a Cisco ASA WebVPN with SSO” you need to do the following:
Configuration -> Remote Access VPN -> Clientless SSL VPN Access -> Portal -> Bookmarks -> Add/Edit your Bookmarks
