title: ADFS doesn't have P3P policy
body: <p>I have application that uses SAML authentication, we have installed AD FS 3.0 on 2012 R2 machine. I think users do get authenticated but there is an issue with it as my application returns error, here is response header that I get:</p>

  <p>Now what the problem is with this, to my understanding user does get authenticated, but yet my application fails to continue. Searching google I found this <a href="https://social.technet.microsoft.com/Forums/windowsserver/en-US/0e667398-6d27-40d2-be7c-b384f27a9d65/adfs-doesnt-have-p3p-policy?forum=winserverDS" rel="noreferrer">link</a>, but this KB is installed on ADFS server. I believe due to P3P error, this is failing. Any suggestions?</p>
