After the March update of freerdp to freerdp-2.0.0~rc4-lp150.2.3.1 in Leap 15.0
no RDP connections to windows RDP hosts is possible.

See bugs #1129319 and #1130168

As workaround I tried Tumbleweed (snapshot 20190314, but there were no relevant
updates in the meantime as far as I can tell).

In Tumbleweed with xfreerdp from package freerdp-2.0.0~rc4-4.1 connections to
windows hosts are working without specific options.

But krdc-18.12.3-1.1 can not connect.
After entering the password in the popup window and hitting enter the
connection immediately terminates.
