title: SAML NameId Policy
body: <p>I am new to the concept of Single Sign On(SSO). I came to know that SAML request and response is the best way to achieve SSO process. I then started reading about SAML2.0. I came around a term <strong>NameIdPolicy</strong> in saml2.0 which was not there in saml1.0. <br><br>
  Definitions say that It is the format of the NameID we request from the IdP.I want to know what is that format is? I mean what data from IDP should come in the format NameIDPolicy specify? Can anyone brief me on this NameIdPolicy concept?</p>
