How to use this project

1. Git clone this project

2. Bundle install

3. Register the SAML entity on your identity provider

   • Go to openidp.feide.no/simplesaml/module.php/metaedit/index.php

   • Click Register New Account and follow instructions

   • Once you’re logged in, click Add New Entity

   • Make up an entity ID

   • Use the same value for the name and description fields

   • Under the SAML 2.0 tab, set the AssertionConsumerService endpoint to something like: localhost:3000/saml/consume

4. Change app/models/account.rb to be something like:

   • settings.assertion_consumer_service_url = “localhost:3000/sessions/complete”

   • settings.issuer = # THE ENTITY ID/NAME YOU ENTERED ABOVE

   • settings.idp_sso_target_url = “openidp.feide.no/simplesaml/saml2/idp/SSOService.php”

   • settings.idp_cert_fingerprint = “c9ed4dfb07caf13fc21e0fec1572047eb8a7a4cb”

5. Run the Rails server

How SAML works

1. You browse to localhost:3000/saml

2. You’re redirected to a URL like openidp.feide.no/simplesaml/saml2/idp/SSOService.php?SAMLRequest=nZNBb9swDIXv%2BxWG7…

3. If you’re not currently logged in at the identity provider, you’ll see a login page

4. After logging in, you might see another “consent about releasing personal information” page that you must click Yes Continue to

5. You’re redirected to POST to localhost:3000/saml/consume with SAMLResponse => “PHNhb”… (a really long encrypted string)

6. The response object will look something like:

response: #<Onelogin::Saml::Response:0xb6e14d74
  @name_id="_8345e8a3b8fb03c55071ffa7320b40eda8523faef2",
  @options={},
  @settings=#<Onelogin::Saml::Settings:0xb6df274c
    @idp_sso_target_url="https://openidp.feide.no/simplesaml/saml2/idp/SSOService.php",
    @name_identifier_format="urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress",
    @issuer="DanielAtQuickLeftComTest",
    @idp_cert_fingerprint="c9ed4dfb07caf13fc21e0fec1572047eb8a7a4cb",
    @assertion_consumer_service_url="http://localhost:3000/sessions/complete">, @document=<UNDEFINED> ... </>,
    @response="PHNhbWxwOlJlc3BvbnNlIHhtbG5zOnNhbWxwPSJ1cm46b2FzaXM6bmFtZXM6dGM6U0FNTDoyLjA6cHJvdG9jb2wiIHhtbG5zOnNhbWw9InVybjpvYXNpczpuYW1lczp0YzpTQU1MOjIuMDphc3NlcnRpb24iIElEPSJ

1. The Rails app then redirects to either complete, or fail if not response.is_valid?

2. The /saml/complete page will show you a NameID like _8345e8a3b8fb03c55071ffa7320b40eda8523faef2 and a link to Logout (logs out from the Rails app not the identity provider)

3. You can logout for real by going to openidp.feide.no/simplesaml/module.php/selfregister/index.php and clicking on Logout
