SUSE Linux 15.3 Eduroam doesn't work with U- or s-number, but does with Science account

February 14, ILS switched off antique versions of TLS (1.0 and 1.1) for the Eduroam authentication on ILS LDAP servers. From then on, SUSE Linux 15.3 clients can’t authenticate with U- or s-number. They only have TLS1.2 and the ILS servers offer TLS1.3 first, after that an error occurs. By using the Science-account to authenticate, these users succeed in connecting to Eduroam.
