This article should get you started: http://www.brianmadden.com/content/article/Configuring-Smart-Card-authentica tion-for-Citrix-Presentation-Server Note, the Web Interface server must be a domain member. There must be no SSL termination between the Citrix client and the Web Interface server (i.e. no proxy of Web Interface through Secure Gateway or Access Gateway. Proxy of ICA through Secure Gateway or Access Gateway is fine).

Is there a document out there that describes how to configure the Web Interface server to allow/require Smart card logons? I know I have to get a certificate for the server, but that's it. Thanks in advance, _________________________ Hector Minero NSWCDD Code K55 Ph: 540.653.8859 Email: hector.minero@xxxxxxxx
