authentication - Configure Okta to Mediate between our SP Application and IdP -


we service provider has saml enabled our app allow idps authenticate users us. make sure on same page

  • identity provider (idp) application job authenticate users
  • service provider (sp) end application federates identities , authentication idp
  • saml protocol allowing idps make trustworthy identity assertions sps. using saml 2.0 (http://en.wikipedia.org/wiki/saml_2.0)

more information on federated identity here: http://developer.okta.com/docs/guides/saml_guidance.html

we using okta idp, have run situation need integrate separate idp. have our app communicate okta , have okta deal talking separate idp , validating assertions. due our particular use case, our app knows underlying idp should used, no need idp discovery.

we configure okta authentication flow follows:

  1. our app redirects user endpoint in okta indicating use underlying idp authentication

  2. okta , underlying idp whatever necessary authenticate user , validate authentication

  3. our app gets single response (via http-post) our acs endpoint authenticating user, signed okta

from end user perspective, navigate service-provider.com, redirected through okta underlying-idp.com, perform necessary authentication, , redirected service-provider.com. end user unaware of middle okta layer, possible exception of okta url briefly appearing in browser address bar during redirects.

so far, have been able set inbound saml in our okta instance users can authenticated in okta via underlying idp. have our app redirect endpoint given in inbound saml configuration page samlrequest, brings users okta dashboard since link authenticating users in okta, not authenticate users sp using okta. see our relevant configuration:

how can configure okta our use case possible? ideally, okta serve middleman or mediator, checking , passing along saml requests/assertions. specifically, don’t need these users authenticated okta users necessarily; need okta assert user based on underlying idp’s assertion.

kinda sounds need idp discovery capability okta has on roadmap later year combined inbound saml setup relationships other idp. believe it's possible sort of implement custom login page. they've mentioned doing professional services, i'd feel lot better when they've built idp discovery platform.
