Hello, I have some client SSL certificate issues on IE, It works OK on Firefox, without any problem. When I try to enter at https web with client cert autentication IE returns me "Friendly generic error" where i cant debug anything, i try to disable it from IE options and add Feature_Enable_Compat_logging on windows register, to get a datailed debug, it doesnt work. How I can debug SSL client cert authentication on IE ? We are working with 2008R2 and IE9. Thanks :)
