salt-formula-shibboleth
=======================

Shibboleth is among the world's most widely deployed federated identity solutions, connecting users to applications both within and between organizations.

Sample pillars
==============

.. code-block:: yaml

  shibboleth:
    server:
      enabled: true
      app:
        entity_id: http://${_param:proxy_vip_address_public}:5000
        signing: false
        encryption: false
      idp_url: "https://saml.example.com/oam/fed"
      idp_metadata_url: "https://saml.example.com/oamfed/idp/metadata"
      attributes:
      - name: test
        id: test

Shibboleth through HTTP proxy
==============
Sometimes there is needed to connect to IdP through HTTP proxy. This has to be done via adding TransportOption to MetadataProvider in Shibboleth2.xml configuration file.

.. code-block:: yaml

  shibboleth:
    server:
      enabled: true
      proxy: http://10.10.10.12:8888


Override IdP metadata from file
==============
Sometimes the metadata is not publicly aviailable from IPD. You can define the metadata in pillar. In this case the idp_metadata_url parameter will be ignored.

.. code-block:: yaml

  shibboleth:
    server:
      idp_metadata_file: |
        <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
        <EntityDescriptor xmlns:xsi="https://www.w3.org/2001/XMLSchema-instance" xmlns="urn:oasis:names:tc:SAML:2.0:metadata"
        entityID="idp_url">
        <IDPSSODescriptor
        WantAuthnRequestsSigned="false"
        protocolSupportEnumeration="urn:oasis:names:tc:SAML:2.0:protocol">
        <KeyDescriptor use="signing">
        <ds:KeyInfo xmlns:ds="http://www.w3.org/2000/09/xmldsig#">
        <ds:X509Data>
        <ds:X509Certificate>MIIEADi........==</ds:X509Certificate>
        </ds:X509Data>
        </ds:KeyInfo>
        </KeyDescriptor>
        <KeyDescriptor use="signing">
        <ds:KeyInfo xmlns:ds="http://www.w3.org/2000/09/xmldsig#">
        <ds:X509Data>
        <ds:X509Certificate>MIIEADi........==</ds:X509Certificate>
        </ds:X509Data>
        </ds:KeyInfo>
        </KeyDescriptor>
        <!-- Supported Name Identifier Formats -->
        <NameIDFormat>urn:oasis:names:tc:SAML:2.0:nameid-format:transient</NameIDFormat>
        <!-- AuthenticationRequest Consumer endpoint -->
        <SingleSignOnService
        Binding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST"
        Location="https://IDP_URL/SAMLLogin"
        />
        </IDPSSODescriptor>
        </EntityDescriptor>


Shibboleth session control
==============
Sometimes there is needed to tune session settings for the application. This has to be done via setting sessions variables Shibboleth2.xml configuration file.

.. code-block:: yaml

  shibboleth:
    server:
      sessions:
        lifetime: 28800
        timeout: 3600
        relaystate: "ss:mem"
        checkaddress: "false"
        handlerssl: "false"
        cookieprops: "http"


Shibboleth attributeresolver/regex plugins support
==============
Sometimes there is needed to set add new attribute by extracting some information from other attributes.  This has to be done loading the plugin and a adding attributeresolver with transform type in Shibboleth2.xml configuration file.
See more detail here: https://wiki.shibboleth.net/confluence/display/SHIB2/NativeSPAttributeResolver#NativeSPAttributeResolver-TransformAttributeResolver(Version2.5andAbove)

.. code-block:: yaml

  shibboleth:
    server:
      outofprocess:
        extensions:
          library:
            plugin1:
               path: plugins.so
               fatal: "true"
      attributeresolver:
        transform:
          Email:
            mantch1:
              match: "@.*$"
              destination_name: "User-identifier"
              destination: "$1"
            mantch2:
              match: "@.*$"
              destination: "$2"
Shibboleth shared session
==============
Sometimes there is needed to set shibd on each controller where keystone is running. To make sure sessions are accessible and shared between all of them you need to setup shared storage for sessions
The example below shows you how to setup shared storage using memcached available on controllers:
Please note that sessioncache requires memcached with bitmap set to true. Omitting sessioncache element will result in an in-memory plugin identified as id="mem".

              fatal: "true"
      storageservice:
        mc:
