ACS 5.5 and Windows 2012 AD support

Hi All,

previously I had two AD domains based on 2008 and had machines in one domain and users in another domain

and the condition statement "Was machine authenticated=True" worked fine when doing EAP-TLS machine then user

authentication.

I have now upgraded the machine's domain to 2012 and  machine authentication works fine and user authentication

also works, but when you put the two together, and enable "Was machine authenticated=True" the ACS errors

out when doing user authentication with the message "ACS unable to find previous successful machine authentication"

even though machine authentication was successful. I have tried with with ACS being a member of both 2008 and 2012 domains at each stage.

The clients are all windows 8.1

Has anyone encountered this scenario before ?

TIA
