My Server is Windows 2008.
Mr. X is accessing my web server using Mr. X's certificate. In that time, an outsider is also trying to access my server using Mr. X's certificate (somehow he got it). Is it possible to disable multiple access using one certificate?
N.B: I mapped 900 certificates to my SSL-enabled server which was one-to-one mapping. No one else will be allowed to access my server. I used one user account to map all 900 certificates. But while testing I found that I can access my server from two different PCs using one client certificate at the same time. How can I resolve it? It would great if anyone can help me regarding this.
