Maintenance work: Exchange of TU-LDAP server certificates

On 24.11.2022 from 7.00 to 8.00 a.m.

2022/11/21

+++ Update from 24.11.2022: Maintenance successfully completed. +++ The TLS certificates of the central user directory TU-LDAP are expiring. Therefore, the HRZ will replace the certificates on Thursday, November 24, 2022.

The certificates will be obtained via the TCS offering from GÉANT. Therefore, the underlying root certificate will change. Root certificates used by TCS can be found here.

If you are running a service that accesses the TU-LDAP, please check that certificates under the root certificates listed there will be accepted at the time of changeover.

If there are any questions or problems on the day of the changeover, please contact service@hrz.tu-… with the subject “TU-LDAP certificate renewal”.

You can find more information on the topic of server certificates on our corresponding web pages.
