The certificate of the central LDAP service (ldap-lzr.zih.tu-dresden.de) will be renewed on Tuesday, 18 November 2025, 2:00 to 2:15 p.m. The CA (certificate authority) will change, as the new certificate is issued by Harica.

The administrators of the systems connected to LDAP have already been informed by e-mail about the changeover and made aware of any measures that may be necessary. Information on how to deal with the certificate changeover can be found in the following FAQ article: https://faq.tickets.tu-dresden.de/v/ItemID=821
