Bug 503355

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
