10.5.3 changed Safari's behavior so that the users are prompted to select a certificate before sending it to a web server. The first time a user makes this choice, an identity preference is set in the user's keychain, linking the certificate to that web page. Unfortunately, this change introduced a bug that prevented Safari from connecting to certain websites that required a personal certificate. Apple fixed this issue in 10.5.4, but instead of being prompted to select a certificate, the user must manually configure the identity preference for such website.

CertAid simplifies this process by configuring identity preferences for a list of MIT websites that are known to be problematic.

If after running this tool, you are still unable to connect to a certificate protected website, launch Keychain Access and delete any identity preferences that may be set for the website, then re-run CertAid.
