Add .RDP files support

[nwildner]

Hi. Newer FreeRDP(git-2014 and newer) releases support .rdp files for Win2012 and 2016 servers that have self-contained connection and load balancing features with RDS+connection brokers that point to multiple servers on a cluster.

Besides all these fancy names/concepts/buzzwords, using these files as a parameter should be enough to make the connection work withouth declaring servers . Example:

xfreerdp /home/tc/FILE.rdp /d:DOMAIN /u:user /p:pass /kbd:"Portuguese (Brazilian ABNT2)"

Would it be possible to implement something like a RDPConnectionFiles parameter to make this work?

[DEFAULT]
RDPBinary = xfreerdp
RDPDomain = Domain
RDPConnectionFiles = /home/path/to/RDPOffice1.rdp  /home/path/to/RDPOffice2.rdp  /home/path/to/RDPOffice3.rdp
RDPDomainFlags = /d:
RDPServerFlags = /v:
RDPUserFlags = /u:
RDPPasswordFlags = /p:
RDPDefaulfFlags = /cert-ignore /f
RDPExtraFlags = /sound:sys:pulse /rfx /fonts

This way we can:

• Deploy one image that has all clusters information
• User will not have to know server names cause the RDP files will handle the connection to brokers, and these will make the load balance work on the servers of that cluster/location/office.

Hey @nwildner I don't know if this feature is still wanted but I have edited the code to do this for our organization. Are you still interested in this if I would create a PR?

support for this available here https://github.com/justmatt25/RDPGUI

I would create a PR but I don't know that it is backwards compatible and also I am not sure what would happen if you try to use it without the .rdp file.

This is a nice feature to have with this interface.
