Hi guys, I've setup a new proxy array and most things seem to work fine. I have enabled integrated authentication and set a web access rule to allow HTTP, HTTPS and FTP out to the internet for all "Domain Users". Users can access the internet and I can see the user names under "monitoring" / sessions.
The problem I'm facing is, when users try to access a citrix page, they can log in to the front portal but when they try to launch an application they are prompted for credentials "Proxy authentication required". The message shows the IP address of the array and mentions "NTLM".
To get things working I've added the "All users" to the web access policy which has fixed the problem, of course this is not ideal as security is a little loose now and all sessions under monitoring shows "anonymous" against every connection.
What could be causing the prompt for credentials?
Any advice or suggestions would be much appreciated.
