A few days ago Chrome stopped accepting my CA certificates. Now it just says:
Invalid Server Certificate You attempted to reach my-domain, but the server presented an invalid certificate.
Here's a screengrab:

I'm running Chrome 11.0.696.57 on OS X. I've also tried this with Chrome 10.0.648 on Ubuntu. Under Safari and Firefox I'm able to access the site without problems.
BTW, I have already installed the certificate file in my Keychain (under System keychains.)
Can anyone shed some light on what I'm doing wrong? How do I let Chrome enter this site?
