Linux – How to enable login as root on xrdp with centos and GNOME

Was wondering if anyone knows how to enable root login on xrdp with GNOME and centos 6?

Below is my config for /etc/xrdp/xrdp.ini

[globals]
bitmap_cache=yes
bitmap_compression=yes
port=3389
crypt_level=high
channel_code=1
max_bpp=24
#black=000000
#grey=d6d3ce
#dark_grey=808080
#blue=08246b
#dark_blue=08246b
#white=ffffff
#red=ff0000
#green=00ff00
#background=626c72

[xrdp1]
name=sesman-Xvnc
lib=libvnc.so
username=ask
password=ask
ip=127.0.0.1
port=-1

Below is my config for /etc/xrdp/sesman.ini:

[Globals]
ListenAddress=127.0.0.1
ListenPort=3350
EnableUserWindowManager=1
UserWindowManager=startwm.sh
DefaultWindowManager=startwm.sh

[Security]
AllowRootLogin=1
MaxLoginRetry=4
TerminalServerUsers=tsusers
TerminalServerAdmins=tsadmins

[Sessions]
X11DisplayOffset=10
MaxSessions=10
KillDisconnected=0
IdleTimeLimit=0
DisconnectedTimeLimit=0

[Logging]
LogFile=/var/log/xrdp-sesman.log
LogLevel=DEBUG
EnableSyslog=0
SyslogLevel=DEBUG

[X11rdp]
param1=-bs
param2=-nolisten
param3=tcp

[Xvnc]
param1=-bs
param2=-nolisten
param3=tcp
param4=-localhost
param5=-dpi
param6=96

Works with a regular user however either root or a user I have given root privileges to won't login.

Before someone says I shouldn't login as root, this is a test environment and I need to be able to.

Cheers
