For example: + +.. code-block:: bash + + $ apt-get install libapache2-mod-auth-mellon + +Configure your Keystone virtual host and adjust the config to properly handle SAML2 workflow: + +Add *WSGIScriptAlias* directive to your vhost configuration:: + + WSGIScriptAliasMatch ^(/v3/OS-FEDERATION/identity_providers/.*?/protocols/.*?/auth)$ /var/www/keystone/main/$1 + +Make sure the *wsgi-keystone.conf* contains a ** directive for the Mellon module and +a ** directive for each identity provider:: + + + MellonEnable "info" + MellonSPPrivateKeyFile /etc/httpd/mellon/http_keystone.fqdn.key + MellonSPCertFile /etc/httpd/mellon/http_keystone.fqdn.cert + MellonSPMetadataFile /etc/httpd/mellon/http_keystone.fqdn.xml + MellonIdPMetadataFile /etc/httpd/mellon/idp-metadata.xml + MellonEndpointPath /v3/OS-FEDERATION/identity_providers/idp_1/protocols/saml2/auth/mellon + MellonIdP "IDP" + + + + AuthType "Mellon" + MellonEnable "auth" + + +.. NOTE:: + * See below for information about how to generate the values for the + `MellonSPMetadataFile`, etc. directives. + * ``saml2`` may be different in your deployment, but do not use a wildcard value. + Otherwise *every* federated protocol will be handled by Mellon. + * ``idp_1`` has to be replaced with the name associated with the IdP in Keystone. + * You are advised to carefully examine `mod_auth_mellon Apache + configuration documentation + `_ + +Enable the Keystone virtual host, for example: + +.. code-block:: bash + + $ a2ensite wsgi-keystone.conf + +Enable the ``ssl`` and ``auth_mellon`` modules, for example: + +.. code-block:: bash + + $ a2enmod ssl + $ a2enmod auth_mellon + +Restart the Apache instance that is serving Keystone, for example: + +.. code-block:: bash + + $ service apache2 restart + +Configuring the Mellon SP Metadata +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Mellon provides a script called ``mellon_create_metadata.sh`` which generates the +values for the config directives `MellonSPPrivateKeyFile`, `MellonSPCertFile`, +and `MellonSPMetadataFile`. It is run like this: + +.. code-block:: bash + + $ mellon_create_metadata.sh http://keystone.fqdn:5000 \ + http://keystone.fqdn:5000/v3/OS-FEDERATION/identity_providers/idp_1/protocols/saml2/auth/mellon + +The first parameter is used as the entity ID, a unique identifier for this +Keystone SP. You do not have to use the URL, but it is an easy way to uniquely +identify each Keystone SP. The second parameter is the full URL for the +endpoint path corresponding to the parameter `MellonEndpointPath`. + +Fetch your Service Provider's Metadata file. This corresponds to the value of +the `MellonIdPMetadataFile` directive above. For example: + +.. code-block:: bash + + $ wget --cacert /path/to/ca.crt -O /etc/httpd/mellon/idp-metadata.xml \ + https://idp.fqdn/idp/saml2/metadata + +Upload your Service Provider's Metadata file to your Identity Provider. This +is the file used as the value of the `MellonSPMetadataFile` in the config, +generated by the `mellon_create_metadata.sh` script. The IdP may provide a +webpage where you can upload the file, or you may be required to submit the +file using `wget` or `curl`. Please check your IdP documentation for details. + +Once you are done, restart the Apache instance that is serving Keystone, for example: + +.. code-block:: bash + + $ service apache2 restart -- cgit 1.2.3-korg
