Configuring Mac OS X 10.5 (Leopard) for eduroam

Installing the Certificate

The Add Certificates dialogue box will open and ask you if you want to add the certificate to a keychain. Select either login or system from the Keychain drop-down and click OK.

You will then see a dialogue asking if you want to trust certificates signed by "NetworkSupportRootCA" from now on. If you want to set them to Trusted status, click on 'Always Trust'. (If you don't do this, you'll see a warning message every time you connect to eduroam at QMUL.)

You will be prompted to enter your local password to authorise the change. Enter your account password for the machine you're using. You may need to do this more than once; if nothing seems to happen after the first time you enter your details, check that there is not a second prompt open on your desktop.

Configuring a wireless connection

  • Click on the Airport icon on the menu bar (and select Turn AirPort ON if necessary) to see a list of available wireless networks.
  • Select 'eduroam' from the list.

If a dialogue appears warning you that: "The server certificate is signed by an unknown root certificate authority", you should check the certificate and satisfy yourself that this is the correct network. To do this, click on 'Show Certificate'.

The Verify Certificate window will expand to display more details. The correct certificate is, with an expiry date of 13/5/2018.

Above the certificate pane you will see a 'chain of trust' going back to "NetworkSupportRootCA".

If you see a different chain, you are connecting to an unknown server and you should not continue.
If you see the chain but red circles with crosses appear against each entry, the root certificate has not been installed correctly.

You can prevent the warning message "This certificate was signed by an untrusted issuer" by checking 'Always trust these certificates'.
