[keycloak-user] Cannot get SPNEGO authentication working

Thanks Bruno.
Neither of these really helped. I've been doing a lot more research and now I believe the problem is my browser is sending back a NTLM token instead of the Kerberos ticket. When I run it with fiddler I see the 401 response from keycloak with the WWW-Authenticate: Negotiate header. The next request then sends the Authorization: Negotiate TIRMTVNT..... I believe this is the NTLM token since it starts with TIRM.
We are using JDK 1.8u31, windows 2012 on the keycloak server, and windows 2008 R2 on the AD server and keycloak 2.0.0 Final

Hi Timothy,
I found something related to your issue here[1]. There's also some old discussion about it[2]. If that does not help, please provide more details about your setup like: JDK, Keycloak and Windows version.
