Security Certificate for Catalogue Access

For your security we offer the OPAC SSL-encrypted and use an SSL certificate of the German Research Network (DFN) issued by the Gesellschaft für wissenschaftliche Datenverarbeitung Göttingen (GWDG). The SSL certificates of the DFN have been authenticated by the Deutsche Telekom, but the Telekom certificate is not yet included as standard in all browsers.

With the newer browser versions the handling of unknown certificates has been tightened. With every check, error messages appear, e.g. "Secure connection failed" or similar, although our certificate is valid and the connection is secure.

You can eliminate the occurrence of such messages by adding the certificate as an exception in the browser and saving it permanently
