eduroam offers world-wide roaming access for members of educational and research institutions. A member of such institution can obtain network access at any other member institution using his/her eduroam ID. This is implemented through a network of Service Points (which control the WiFi access) and Identity Providers (which identify and authorize the users). Typically, an eduroam member institution is both Service Point and Identity Provider simultaneously - this is also the case for HITS.
In case of problems, please contact the ITS group.
As HITS has a domain name (h-its.org) which is not part of the normal German domain hierarchy (.de), the other member institutions have to implement the so-called Dynamic Discovery in order to properly route the authentication requests for HITSters - this is known to work in most European institutions. If Dynamic Discovery is not implemented at the visiting institution, it is not possible to reach the HITS authentication server, the authentication requests will remain unanswered, and therefore the access to the eduroam network to be rejected. Unfortunately this is a decision made at the visiting institution and there is nothing that can be done about it elsewhere.
