I have set up Active Directory on my Mac and I can log in and authenticate fine to the server. When I try to browse the Internet, there is an error which says "The user could not be determined by the Single Sign-on agent". I believe the Internet is filtered through Bluecoat, so I was wondering how to browse the Internet as it's trying to request my Active Directory username but the browser is not picking it up.

I've had a look at the settings in Safari, but I just can't see anything about this.

I tried using Authoxy but I still can't browse or go to the app store. I have no problems with Active Directory as I can log in and can see all the other computers and servers.

  • This is something you need to ask your IT department about. – EEAA Sep 12 '11 at 15:28
  • I cannot access the App store either because of this. I'm not sure how to configure the account to be able to access Internet once I log in via Active Directory. – fes Sep 12 '11 at 15:28

Sounds like your proxy server requires NTLM authentication (this is a way in Windows where the logged in Windows session is used to transparently authenticate to the proxy). Authoxy supports this on OS X.
