This is pertaining to SDL Tridion 2013 SP1. We are not using LDAP, instead Active Directory.

The userids are appearing in the Trustees table as well as correct privileges in the TCM Admin as System Admin.

However we are still getting this error below:

Server Error

401 - Unauthorized: Access is denied due to invalid credentials. You do not have permission to view this directory or page using the credentials that you supplied.

Browser Error

Any thoughts on why this error would be occurring?

We can also log into our sandbox with our AD credentials on a Windows 2008 vm, but we cannot login with our AD credentials on a Windows 2012 vm..

Here is a picture of the Tridion Logs:

  • Anything in the event log? What browser are u using? Does it prompt you for username? Do you enter domain as well? – Andrey Marchuk Feb 27 '15 at 16:05
  • I have tried both with domain\username and strictly username. I have tried all browsers, IE specifically I can see the Server Error, the others just spin and try to load..checking the event log now – Andrew William Ross Feb 27 '15 at 16:09
  • @user978511 - Do these pictures help at all? Or do you need system or application event logs? – Andrew William Ross Mar 2 '15 at 21:34
  • It has something to do with IIS, check IIS logs, also check Tridion application pool settings. Did you change any web.configs, or anything in the IIS? It looks to me that it's either web.config or IIS misconfiguration, IIS security issue, or some of the required windows components was not installed. – Andrey Marchuk Mar 3 '15 at 7:54
  • Can you please check if the user NT AUTHORITY\NETWORK SERVICE is added in Impersonation Users – Prasoon Srivastava Mar 3 '15 at 16:40

I appreciate everyone's input on this error. The only setting that needed to be changed was the User Right Assignment setting by adding Authenticated Users. I have updated the test GPO to only include this setting and it appears to be working as expected.
