Hello
Thank you for your inquiry and welcome to Centrify.
From the information you given, there are a few points that might have this failed:
1) If you have verified the certificate are valid from keychain access, there should not be anything Centrify will change after that. Therefore, I suspect if the problem is with the browser itself. Please see the following:

- https://discussions.apple.com/thread/6431361?tstart=0
Please see the solution above and see if that would help resolving the issue. Meanwhile, if posssible, please take a screenshot of the certificate from keychain access for us to double check as well. Thank you!
BR,
Ivan
