And maybe it won't be trusted because you don't have the root cert. Vista may contain something different to your Citrix (Windows 2003?) servers. There are two MS tools I use for automating the certificate import so that users never need to deal with this stuff. Certmgr.exe and winhttpcertcfg.exe. http://weblogs.asp.net/hernandl/archive/2005/02/09/WinHttpCertCfgTool.as px I hope that goes someway to helping. Cheers, Jeremy.

Open up the certificate details when you get the prompt, go to the last tab, I think its "Certification Path", and look at the trust chain. You'll see the certificate that's being presented and potentially another certificate above it that is the parent, or root of this one. One or both of those will probably have a red X next to them. If so download and install that/these certificates in the computers trusted or intermediate trust stores. The prompt essentially means "Hey, the server you're talking to is passing a server certificate that I don't trust. Are you sure you want to start a dialog?" If you install the certificates the computer will then implicitly trust the server. Additionally, I believe each user has their own certificate store, so you may need to install in the computer's store for them to be global. Otherwise I don't believe it has anything to do with roaming profiles and Vista probably remembers the user's first response to the prompt. Give that a try.

I have users running Vista and they have a local profile and when they accept the cert they only do it once. -----Original Message----- From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Braebaum, Neil Sent: 16 January 2009 11:41 To: thin@xxxxxxxxxxxxx Subject: RE: [THIN] Certificates and profiles Why do they have to accept the cert?

Neil ________________________________ From: thin-bounce@xxxxxxxxxxxxx on behalf of Hamilton, Ronnie Sent: Fri 1/16/2009 11:24 AM To: thin@xxxxxxxxxxxxx Subject: [THIN] Certificates and profiles HI, We have recently implemented a new web application which requires you to accept a certificate when you open the web page to access the site. My question is when the user has accepted this and logs out and then back in they have to accept it again. We currently use roaming profiles and I was under the impression that this setting should be held.
