The attempt to access a WebDAV share, which is secured with a SSL client certificate fails completely. You can't even import or choose a client certificate in KDE. Reproducible: Always Steps to Reproduce: 1. Configure a WebDAV share with mandatory SSL client certificate validation e.g. with Apache mod_dav 2. Start Dolphin 3. Add a new WebDAV connection with SSL in Dolphin Actual Results: The connection is refused. Apache reports: "AH02261: Re-negotiation handshake failed: Not accepted by client!?" Expected Results: KIO should ask for SSL client certificate. KDE should provide a way to import SSL client certificates. Tested with Dolphin 16.04.2 KDE Plasma version: 5.6.4 KDE Frameworks version: 5.23.0 Qt Version: 5.6.1 Distribution: openSUSE Tumbleweed (20160625) (x86_64)
Please, could this be a cause of Dolphin not presenting an authentication dialogue? Consider https://bugs.kde.org/show_bug.cgi?id=305952
