title: Top SAML 2.0 identity providers in the market
body: <p>I am working on a product (service provider) which uses SAML 2.0 for authentication purpose. Having said that I wanted to know what you all think are the top and most trusted identity providers that are in the market, that supports SAML 2.0 and if there is any data sheet available on the facts related to the top identity providers used today.</p>
  
  <p>I have used Oracle's Identity Federation and IBM Tivoli. I have also got good reviews about siteminder.</p>
  
  <p>thanks<br>
