Publishing RD Web Access on Forefront TMG 2010 with TMG FBA

Hi,

I'm trying to publish RD WebAccess on TMG server and to have the users authenticate with TMG's Forms based authentication. The web access rule in TMG is configured for NTLM authentication delegation. But I end up hitting the RD webaccess authentication forms, after I complete authentication with the TMG's forms. Is there anyway I can avoid the RD web access forms and authenticate the users only with the TMG's forms.

Both RD-WA and the TMG server run on Win Server 2008 R2.

Any info on this will be much appreciated !
