** Description changed:

- If LightDM receives and XDMCP ForwardQuery it currently ignores it. It
- should send back a Willing to the address specified in the query
- request.
+ [Impact]
+ LightDM ignores the XDMCP ForwardQuery request.
+ 
+ [Test Case]
+ 1. Set up XDMCP so queries are forwarded through a server
+ 2. Connect to LightDM
+ 
+ Observed result:
+ Connection fails
+ 
+ Expected result:
+ Connection succeeds.
+ 
+ [Regression Potential]
+ Some risk of existing XDMCP queries being broken by the change. Checked with regression tests.
