Dennis,

I can think of two solutions:

1) Put a RADIUS server that is capable of stripping REALMs in front of your ACS 
5.x server (e.g. FreeRADIUS)
    (this will also help you with other features in the future that FreeRADIUS 
tends to integrate and ACS doesn’t)

2) add to AD a second UPN (@uogelph.ca <http://uogulph.ca/>)
