We are facing an issue where we don't get SSO to work on an IIS web app. We have set Windows-Authentication as enabled and Negotiate and NTLM as providers (IIS Windows Authentication and Providers). We have the same setup on a test-environment where SSO works perfectly. Now I have tried to do a cap of one session (Session capture). The cap, to me, doesn't show much, only that my system is trying to do an HTTP GET 4 times before doing the negotiation and choosing NTLM. Somehow Kerberos is not being used and I don't get a "klist" ticket of the SSO (on the test-environment I get a ticket). I have no clue where to start looking for that problem.
I really appreciate any help you can provide.
If there is anything more I need to add please let me know.
Best, Niclas
