Univention Bugzilla – Bug 55611
Mac clients reject UCS SSL host certificate because Apple limited maximum validity
Last modified: 2023-01-31 15:41:04 CET
https://support.apple.com/en-us/HT211025 says "TLS server certificates issued on or after September 1, 2020 00:00 GMT/UTC must not have a validity period greater than 398 days." UCS default: ssl/validity/host: 20624 I guess we should at least mention how to handle this in the documentation.
