You should get a popup that describes the certificate.
Look for the domain and server name. It should match the site you expect, e.g.
"admin.triumf.ca" or "trmail.triumf.ca".
It should not be an unexpected TRIUMF
name such as "2-s85-v14-wlan.triumf.ca" or "vistemp2.triumf.ca", or an outside site
such as "triumf.ca-security.ru". The "triumf.ca" should be on the right.
