We've been working with the ASA on 7.x code and now the 8.x code in combination with our Citrix Presentation server now for about a year. It works good, except for the fact we're having to have our users basically login in twice, once for the WebVPN and again for the Web UI for Citrix. If we look at the options in the ASA and Citrix for passthrough, the best we've been able to accomplish is getting the ASA to pass the authentication to the WebUI which will then display the correct published applications for the user, then when the user clicks on app, the user is prompted from a windows user/password screen for the correct authentication. However, if we turn pass-through off.. you log into WebVPN, log into Citrix Web UI, get the apps and it works. As anyone made pass-through authentication work with with the ASA and Citrix? If so, please explain what you did. Thanks
