title: can simplesamlphp have multiple authentication sources used in a single identity provider?
body: <p>I would like to set up simplesamlphp so that when a user enters service provider 1, it uses an identity provider with an sql authentication source that is located on the same server as service provider, preferably with the idp on the same server.</p>
  
  <p>however, when a user enters service provider 2, i would like to use sp2's own separate authentication source, would i be able to config sp2 to use idp1 that is on the same server as sp1, to use a distinct authentication source used only by sp2? or would i have to setup an idp2 on the same server as sp2, and in the web app that offers sp2, tell it to use idp2 as the identity provider that has its own separate sql auth?</p>
  
  <p>thanks for any help.</p>
