Certificate Replacement

The Deutsche Telekom Root CA 2 - certificate expires on 09. Juli 2019

So far the university network used Deutsche Telekom Root CA 2, which expires on 09. Juli 2019. This is why older wifi profiles will not work anymore after we switch our radius-server over to the new certificate.

The replacement for the Deutsche Telekom Root CA 2 certificate is the T-Telesec GlobalRoot Class 2 certificate, which is expires on 09. Oktober 2033.

For a trouble-free transition, we already offer new wifi profiles with the T-Telesec GlobalRoot Class 2 certificate.

These profiles are available on the serviceportal under the following link: Manuals WLAN.

 

Why do we need a certificate?

A network verifies username and password of a user through a radius-server.

To prevent sending this data to untrustworthy authentification servers, the client verifies the trustworthiness of the radius-server by means of the certificate.
