I'm trying to set up an Active Directory Federation Service Relying Party and I get
the following error.
I've tried modifying
the page to allow <pages validateRequest="false"> to web.config and it doesn't make a difference.
Can someone help me out?
Server Error in '/test' Application.
A potentially dangerous Request.Form value was detected from
the client (wresult="<t:RequestSecurityTo...").
Description: Request Validation has detected a potentially dangerous client input value, and processing of
the request has been aborted. This value may indicate an attempt to compromise
the security of your application, such as a cross-site scripting attack. To allow pages to override application request validation settings, set
the requestValidationMode attribute in
the httpRuntime configuration section to requestValidationMode="2.0". Example: <httpRuntime requestValidationMode="2.0" />. After setting this value, you can then disable request validation by setting validateRequest="false" in
the Page directive or in
the <pages> configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case. For more information, see http://go.
