Authenticate Against Identity Provider Assertion

The Authenticate Against Identity Provider assertion authenticates the current credentials against a selected identity provider, using credentials gathered from other credential source assertions (for example, Require HTTP Basic Credentials, Require SAML Token Profile, or Require SSL or TLS Transport). It is similar to the  except that it does not match the authenticated user against any particular user or group.

The
Authenticate Against Identity Provider
assertion authenticates the current credentials against a selected identity provider, using credentials gathered from other credential source assertions (for example, Authenticate User or Group Assertion except that it does not match the authenticated user against any particular user or group.
Use this assertion when you need to separate authentication and authorization, for example:
  • You want to authenticate the credentials already gathered in the policy, but you don't need to authorize that the resulting user is a particular user or member of a particular group.
  • The policy contains many "User" or "Group" assertions. You want to authenticate first so that if it fails, the identity assertions can be skipped, saving processing time.
  • You wish to perform branching based on the results of authentication (for example, "If the authentication fails, do this; otherwise do this...")
