The expiration date of the certificate of our VPNsec service was apparently not yet checked regularly. This made it possible for the certificate to expire. We put a new certificate into place within an hour. Of course we will check this certificate regularly from now on. For Apple/Mac we needed to construct a new mobileconfig, this took some time, because in the meantime RU had moved to a different Certificate Authority. For Apple macOS this was ready at the end of Feb. 4, with a new installation procedure. For Apple iOS (iPhone/iPad) the old profile has to be deleted and a new mobileconfig has to be installed.

Affected : Users of Science VPN and Eduroam based on science account The certificate of the LDAP servers has been replaced this morning, this has also changed the certificate chain. The radius server uses LDAP as authentication backend and in the radius configuration the certificate chain had to be changed too. This was initially overlooked.
