Every time connecting to the secure wireless, Macs are getting a prompt to verify the certificate:
Authenticating to network "Network-Name"
Before authenticating to server "ServerName", you should examine the server's certificate to ensure that it is appropriate for this network.
To view the certificate click 'Show Certificate'.

This is happening on multiple Macs, every time they reconnect to the wireless. I thought it was a cert trust issue, but selecting "Always trust" does not have any effect. Also the cert is signed by DigiCert.
This seems to be a problem on OS 10.11, but I haven't confirmed that previous OSes are able to actually trust the cert. Other OSes are not having this problem.
How can I permanently trust this cert so it remembers it next time I connect? What could be causing this?
