Just a few weeks ago I’ve started using OpenFire (on windows 2008 x64 server) and Spark. Openfire is using AD, and it works with no problem.
Funny thing is that I can use SSO in spark only on Windows XP machines (all x86, not much left now - under 10%) on Vista and Windows 7 (all x64) it does not won’t too authenticate.
The Configure encryption types allowed for Kerberos policy setting is located in Computer Configuration\Security Settings\Local Policies\Security Options.
That probably is the answer (I have now reed some articles about that) - but the one think I hate about Microsoft is their inconsistency. I’m reading this Microsoft Tech Net article (http://technet.microsoft.com/en-us/library/dd560670%28WS.10%29.aspx) and it leads exactly to the same place in Local policy management - but the problem is it differently arranged form the control panel tool - and even using this does not lead to the configuration that you mention. Reading this (http://pronichkin.com/blog/Lists/Posts/Post.aspx?ID=15) leads to Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\Network security: Configure encryption types allowed for Kerberos but I don’t have this option either in Domain Group Policy nor Local Policy. The funny thing is that if the setting has a changed name or location there is no way to search through hundreds of those settings. For now thanks for help if I finally able to find the setting I will let you know.
