I would love to use Korganizer for accessing our work egroupware server with TLS client certification, especially considering that a plasma phone is going to be available next year. If it helps, thunderbird with the lightning and the Cardbook pluginn supports this.
Thank you for reporting this issue in KDE software. As it has been a while since this issue was reported, can we please ask you to see if you can reproduce the issue with a recent software version? If you can reproduce the issue, please change the status to "REPORTED" when replying. Thank you!
Yes, I can confirm that KDE still does not support TLS client certificate authentication.
