Hello,
I have published a couple of sites trough TMG 2010 to the outside world.
They are publish trough https and listener activated for only Certificate Client Authentication. When I test the sites on my windows 7 pro, my Ipad (IOS7) or whatever it works fine. When I try it on my Windows Phone 8.1 (WP8.1) TMG gives a error...
Error code 500 internal server error. The certificate is revoked. (-2146885616)
My WP8.1 is version 8.10.12393.890 and should support the user certificate.
The same certificate is used for ActiveSync on the same phone and works like a charm. This was also with WP8, but the browser did not support the user certificate. Now it does, I believe:http://msdn.microsoft.com/en-us/library/dn643705.aspx
