A generic SAML strategy for OmniAuth.
https://github.com/PracticallyGreen/omniauth-saml
- OmniAuth 1.1+
- Ruby 1.9.2
Use the SAML strategy as a middleware in your application:
require 'omniauth'
use OmniAuth::Strategies::SAML,
: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:
in Gemfile
:
gem 'omniauth-saml'
and in config/initializers/omniauth.rb
:
Rails.application.config.middleware.use OmniAuth::Builder do
provider :saml,
: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
For IdP-initiated SSO, users should directly access the IdP SSO target URL. Set the href
of your application's login link to the value of idp_sso_target_url
. For SP-initiated SSO, link to /auth/saml
.
-
:assertion_consumer_service_url
- The URL at which the SAML assertion should be received. With OmniAuth this is typicallyhttps://example.com/auth/callback
. Required. -
: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_fingerprint
must be present. -
:idp_cert_fingerprint
- The SHA1 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_cert
must 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 https://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. Used during SP-initiated SSO. Optional. -
See the
Onelogin::Saml::Settings
class in the Ruby SAML gem for additional supported options.
