Using rdp-file: protocol security negotiation or connection failure

Hello,

I would like to use rdektop to connect to a windows server from my linux 
box.
To be able to connect i was given a rdp-file. Is it possible to use 
rdesktop with a rdp-file?

The rdp-file looks like this (abbreviated):
=====================================
screen mode id:i:2

redirectprinters:i:1

redirectdrives:i:0

audiomode:i:0

redirectclipboard:i:1

disable wallpaper:i:1

allow font smoothing:i:0

allow desktop composition:i:0

disable full window drag:i:1

disable menu anims:i:1

disable themes:i:0

desktopwidth:i:0

desktopheight:i:0

gatewayhostname:s:XXX.com

gatewayusagemethod:i:1

gatewaycredentialssource:i:4

gatewayprofileusagemethod:i:1

promptcredentialonce:i:1

bitmapcachepersistenable:i:1

negotiate security layer:i:1

use multimon:i:0

full address:s:WES

username:s:xxx\yyy

alternate full address:s:WES

signscope:s:Full Address,Alternate Full Address,Negotiate Security
Layer,GatewayHostname,GatewayUsageMethod,GatewayProfileUsageMethod,GatewayCredentialsSource,PromptCredentialOnce,AudioMode,RedirectDrives,RedirectPrinters,RedirectClipboard

signature:s:AQABAAEAAAD2DwAAM...
=====================================

The version of FreeRDP I'm using is 1.2.0-beta1.

I would appreciate very much if somebody could hint me in the right
direction to get this working.

Thanks a lot,
Stephan
