You need this configured in the Appsrv.ini file of the client to fix this.... EnableSSOnThruICAFile=On On this front is any one else still annoyed that Citrix use INI files for clients. When are they going to give you a machine setting option that is configured by the registry?

We currently have in production NFuse 1.8 up and running. We have been building and testing a Web Interface 2.1 site to put up but we are having a problem. If you go to the site and use the login, then run an application, they get in without having to login again. It pulls the credentials they used to login to the WI site with. If we turn on the Single Sign / Pass Thru where it should pull there workstation credentials when they go to the WI site and give them there apps, they get in and get there apps, but when they run an app, it prompts them to login again. Has anyone seen this before?
