MIT SECURE wireless - iOS Certificate Prompt


Why do I get prompted to accept a certificate when I try to connect to the MIT Secure wireless network from my iPhone, iPad, or iPod touch?


When connecting to the MIT SECURE wireless networks from an iOS device, such as an iPhone, iPad, or iPod touch, you will be prompted with a "Certificate" screen where you will be prompted to accept a certificate described as being "Not Verified". You must select the Accept button before you are able to connect to these secure wireless networks.


This Certificate prompt lets you know that the server you are connecting to and the certificate you are being asked to accept is not necessarily from a "Verified" source. You can connect to the MIT SECURE wireless network by confirming that you are connecting to an MIT server and trusting the Equifax security certificate. To do this:

  1. Confirm that the Radius Server listed at the top of this screen is or
  2. Confirm that the Root CA listed just below this server is AddTrust External CA Root 
    •  If the above matches the certificate details displayed on your iOS device, then you can safely select Accept and begin using the MIT SECURE wireless network. 
    •  If the Radius Server is not or OR the Root CA is not the AddTrust External CA Root, do not select Accept and please notify the Mobile Devices Team or the Security team.
