To manually specify a client certificate be used for a particular website:
- Open Keychain Access (in Applications/Utilities) and find your client certificate. Click the "My Certificates" category to easily see available client certificates.
- Control-click the certificate, then choose "New Identity Preference..." from the contextual menu.
- A sheet appears in the dialog. Type (or paste) the URL of the page that requires the certificate, exactly as it appears in Safari's location field (for example, "https://www.apache-ssl.org/cgi/cert-export").
Note: With Mac OS X 10.5.4 or later, you may specify a partial URL to match any page on a server (for example, "https://www.apache-ssl.org/").
- Choose the certificate from the pop-up menu, then click Add to create the identity preference. (You may need to click the "All Items" category to view the newly created item.)
To change your decision about which client certificate to use for a particular website:
- Open Keychain Access (in Applications/Utilities) and find the identity preference item for the website in question. Tip: Click the "All Items" category and enter the website name in the search field in the upper right corner.
- Open the item and select a different certificate from the pop-up menu.
As an alternative to step 2, you can delete the identity preference item from the keychain. The next time you visit the site with Safari 3 you will be prompted to select your client certificate.
