Actually, upon further inspection, it looks like you guys installed the certificate in the wrong Category.
In Mac, when you click on any keychain, there is a section call Category right under the keychain...
They are the following:
- All Items
- Passwords
- Secure Notes
- My Certificates
- Keys
- Certificates
The important thing here is My Certificates, none of the certs installed by Centrify shows up there at all, they just showed up under Certificates. This would explains why the credentials aren't accessible.
