Hi,
I have published an extended Sharepoint web application through TMG 2010 and at first with ordinary Windows atuthentication it worked just fine. But the thing I wanted to test was to use Azure AD and ACS as the authentication provider. Set it up as instructed on TechNet and internally (LAN) it works perfect now. But when I'm trying to access the site from the internet side it just throws " Internal Server error 500. The request was rejected by the HTTP filter. (12217)"
Normally this is solved by un-checking "Verify Normalization" and "Block high bit characters" but not this time.
I have tried different listeners in TMG, rebuilt the publishing rule and all I can think of. But it just does not work.
I don't even have the filters active on the https protocol and if I activate Web proxy I do not get the option to Configure HTTP. Is this correct or is there something wrong with my TMG.
