I am in desperate need of getting an Openfire/Spark installation working with SSO. Despite carefully trying to follow all of the various guides I could locate, I can't quite get it to go. I was wondering if any one might be willing to help - I would pay you for your time.
I'm running Openfire 4.1.3 and Spark 2.8.3. Everything works without SSO. When I change the SASL.Mechs property to GSSAPI, I can no longer login in with or without SSO. Error from the Spark log is "org.jivesoftware.smack.sasl.SASLErrorException: SASLError using GSSAPI: not-authorized". I'm guessing it's something very simple with the keytab file, gss.conf file, or similar but this is really not my area of expertise and I need this working just as fast as humanly possible.
Please contact me if you would be willing to help - I would greatly appreciate it.
