title: Can we implement SSO federation in ADFS using multiple relying parties?
body: <p>I have a setup where ADFS has multiple Service providers(SP) and ADFS acts as an Identity Provider using Active Directory as a Name ID store.</p>
  
  <p>Now the scenario required is that the user follows the following steps:
  Step1: User tries to access the Application 1 and is redirected to the Identity Provider by the SP1 for authentication.
  Step2: After authentication the user is redirected back to the application along with a SAML response.
  Step3: Now the user wants to access the application 2 and the SP2 redirects the user to Idp but she does not want to be reauthenticated by the IDP. We want to setup Single Sign on so that user does not have to login multiple times.</p>
  
  <p>Is there any way we can configure ADFS so as to build trust between SP's and there is no need for authentication?
  Perhaps there is some configuration to inform ADFS so as to not ask for credentials again?</p>
  
  <p>I have ADFS2.1 on Windows Server R12 as my IDP and I have Oracle weblogic servers being leveraged as Service Providers. My applications are deployed on these weblogic servers.</p>
