SUMMARY KRDC do not connect to rdp hosts that require sec:rdp where xfreerdp does with the appropriate flag /sec:rdp I work at home and often I need to connect to company servers using RDP. I realized that KRDC can not connect to some hosts where xfreerdp can, when using the flag /sec:rdp I mean, the cmd line can be used to connect to any host. Note the use of /sec:rdp xfreerdp /w:1900 /h:1000 /u:'mydomain\myuser' /p:obfuscated /sec:rdp /v:ip-of-remote-host krdc can not connect to the same host. In hosts that xfreerdp can connect to without using /sec:rdp flag, than, krdc can connect to. SOo I suppose that krdc is missing the /sec:rdp equivalent flag. STEPS TO REPRODUCE 1. try to connect to a rdp server that xfreerdp can connect to only if using /sec:rdp 2. OBSERVED RESULT it will not connect to. EXPECTED RESULT a successful connection SOFTWARE/OS VERSIONS Operating System: openSUSE Tumbleweed 20250417 KDE Plasma Version: 6.3.4 KDE Frameworks Version: 6.13.0 Qt Version: 6.9.0 Kernel Version: 6.14.2-1-default (64-bit) Graphics Platform: Wayland Processors: 12 × AMD Ryzen 5 7600X 6-Core Processor Memory: 30.6 GiB of RAM Graphics Processor: AMD Radeon RX 6600 ADDITIONAL INFORMATION Internet is plenty of similar issues with krdc, for years !
