Bill et al, I am sorry. Here is the log. 2011-02-14 14:46:21,955 INFO [org.jasig.cas.authentication.AuthenticationManagerImpl] - <AuthenticationHandler: org.jasig.cas.support.spnego.authentication.handler.support.JCIFSSpnegoAuthenticationHandler failed to authenticate the user which provided the following credentials: Principal is null>
I shouldn't assume that this information is useless or not required. It didn't provide me with much:) Tom Go Hoos!

Second, if you could post an example log snippet from an authentication attempt, it might be a little easier to suggest where to look for potential solutions... the "Principal is null" message could have several different causes. - Bill On Mon, Feb 14, 2011 at 2:20 PM, Healey, Thomas <[email protected]<mailto:[email protected]>> wrote: All, As you may know since Windows 7 came out it has been broken regarding SPNEGO and CAS environments running on Windows Server 2003. What used to happen was when a authenticated domain user went to an CAS protected site the user would be seamlessly authenticated and forwarded onto the app to be authorized and, if authorized, sent to the site. Now I get "Principal is null" message in the CAS logs and the user is forwarded to the CAS login page. I searched the web for other instances of this problem but those people who are having problems with Windows 7 and CAS/SPNEGO were having a problem with the version of Java they were using and they were getting the following in their logs: "GSSException: Channel binding mismatch (Mechanism level: ChannelBinding not provided!)" from https://wiki.jasig.org/display/CASUM/SPNEGO This is not our problem as we have upgraded the Java version many moons ago. It also suggests a MS webpage http://support.microsoft.com/?scid=kb%3Ben-us%3B968389&x=10&y=18 for further guidance but that didn't help when I tried it. I have also tried to use Windows Server 2008 but no luck. Any thoughts or other areas I can look for answers? -- Bill Markmann Counterpoint Consulting, Inc.
