Common Information
Like the TU Chemnitz institutions worldwide participate in eduroam. This means: If you visit another university that also supports eduroam, you can use the wireless network access there with your TU Chemnitz configuration. And likewise, guests of the TU Chemnitz can connect to our wireless network with their “home institution configuration”. Depending on the institution-specific policies extended or reduced ressources may be provided to the users.
Eduroam is an international RADIUS-based infrastructure that uses 802.1X security technology to roam users between all participating institutions.
The TU Chemnitz configuration uses app and device passwords [de] and a specific certificate chain [de] for the RADIUS server exclusively from October 2018 on. For security reasons a connection using your user acount and your URZ password is not possible. The manual configuration of a secure eduroam access is complex or even not fully possible on some devices. Therefore we provide tool support. The configuration made with our tools ensures that the initial connection will be with our RADIUS server, and only to our RADIUS server your credentials will be sent.

iexplore.exe
and open the TUC IdM portal.
