My environment:
Windows 2008 R2 Domain
Windows 7 client
I have added CA root certificate to local computer store on controllers as well as the client. I have also added root CA and all intermediate CAs to NTAuth store. I don't have any issue in viewing the certificate on both DCs and the client. However when i try to login using that card i get an error message saying "An untrusted certificate authority was detected while processing the smart card certificate used for authentication" I am quite sure the card is valid but i am not able to make out what might be causing this error to occur, any idea?
