Hi List, I am working on implementation of LDAP client where in there is requirement to validate the server's ssl certificate. This is similar to what browser does in case of ssl enabled website. After reading few articles over net I came to know that following checks needs to be done for verfication of ssl certificate. 1) Check if certificate is not expired. 2) Common name on the certificate matches the DNS name of the server. 3) Checks if the CA is trused. I don't know how to perform the check for 3rd step. How can we ensure that CA is trusted? One of my colleague told that I have to store all trusted root certificates and then compare incoming certificate with existing ones.. Is there any better way to check this ...? Also I was told that certificate validation is done to prevent the SSL-MITM attack Is this the only reason or is there any other reason for which the SSL certificate validation is done ? It will be great if you can throw some light in this matter. Any links to relevant websites will do as well.
