I have an ACS namespace with a WS-Federation identity provider installed. Since I use Visual Studio 2012, I used the Identity and Access Tool to create a relying party. The tool uses the realm and return url values that I give them when it creates the relying party (I use the URL of the Azure cloud service where I deploy my project, i.e. http://myapp.cloudapp.net ). There is only one rule in the rule group for my relying party after starting the tool. Go through all the complaints about the [Relying Party]. I tested ACS for my application with only one rule, and also after creating all the rules for the WS-Federation identity provider.
Regardless of the rules in the rule group, I get an error in the title of my question. My browser is redirecting to ACS, however for some reason it cannot find the right relying side. I created the ACS namespace, identity provider and relying party on two different Azure accounts with exactly the same result.
I also tried publishing my Azure cloud service project with http and https endpoints, and both endpoints give the same result.
WS-federated provider identity federation metadata comes from Windows Azure Active Directory.
UPDATE FederationConfiguration section of web.config:
<federationConfiguration>
<cookieHandler requireSsl="false" />
<wsFederation passiveRedirectEnabled="true" issuer="https://[MyNamespace].accesscontrol.windows.net/v2/wsfederation" realm="http://[MyApp].cloudapp.net/" requireHttps="false" />
</federationConfiguration>
