An XML & SAML strategy for OmniAuth integration with ADFS 2.0.
- OmniAuth 1.0+
- nokogiri 1.5
- Ruby 1.9.2
Use the SAML strategy as a middleware in your application:
require 'omniauth' use OmniAuth::Strategies::SAML_RSTR, :assertion_consumer_service_url => "consumer_service_url", :issuer => "issuer", :idp_sso_target_url => "idp_sso_target_url", :idp_cert => "-----BEGIN CERTIFICATE-----\n...-----END CERTIFICATE-----", :idp_cert_fingerprint => "E7:91:B2:E1:...", :name_identifier_format => "urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress"
or in your Rails application:
Rails.application.config.middleware.use OmniAuth::Builder do provider :saml_rstr, :assertion_consumer_service_url => "consumer_service_url", :issuer => "rails-application", :idp_sso_target_url => "idp_sso_target_url", :idp_cert => "-----BEGIN CERTIFICATE-----\n...-----END CERTIFICATE-----", :idp_cert_fingerprint => "E7:91:B2:E1:...", :name_identifier_format => "urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress" end
:assertion_consumer_service_url- The URL at which the SAML assertion should be received. With OmniAuth this is typically
:issuer- The name of your application. Some identity providers might need this to establish the identity of the service provider requesting the login. Required.
:idp_sso_target_url- The URL to which the authentication request should be sent. This would be on the identity provider. Required.
:idp_cert- The identity provider's certificate in PEM format. Takes precedence over the fingerprint option below. This option or
:idp_cert_fingerprintmust be present.
:idp_cert_fingerprint- The SHA256 fingerprint of the certificate, e.g. "90:CC:16:F0:8D:...". This is provided from the identity provider when setting up the relationship. This option or
:idp_certmust be present.
:name_identifier_format- Describes the format of the username required by this application. If you need the email address, use "urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress". See http://docs.oasis-open.org/security/saml/v2.0/saml-core-2.0-os.pdf section 8.3 for other options. Note that the identity provider might not support all options. Optional.
