Issuing SAML Assertions hard-coded in the RADIUS Server
Issuing SAML Assertions hard-coded in the RADIUS Server
Create the file
/etc/freeradius/policy.d/moonshot
(on RHEL platforms, create/etc/raddb/policy.d/moonshot
):moonshot_saml.post-auth { if (&request:Realm == 'YOUR_REALM_HERE') { update reply { SAML-AAA-Assertion = '<saml:Assertion xmlns:saml="urn:oasis:names:tc:SAML:2.0:assertion" IssueInstant="2011-03-19T08:30:00Z" ID="foo" Version="2.0">' SAML-AAA-Assertion += '<saml:Issuer>urn:mace:incommon:osu.edu</saml:Issuer>' SAML-AAA-Assertion += '<saml:AttributeStatement>' SAML-AAA-Assertion += '<saml:Attribute NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:uri" Name="urn:oid:1.3.6.1.4.1.5923.1.1.1.7"><saml:AttributeValue>moonshot</saml:AttributeValue></saml:Attribute>' SAML-AAA-Assertion += '</saml:AttributeStatement>' SAML-AAA-Assertion += '</saml:Assertion>' } } }
Example
Camford University's SAML assertion would look like this:
moonshot_saml.post-auth { if (&request:Realm == 'camford.ac.uk') { update reply { SAML-AAA-Assertion = '<saml:Assertion xmlns:saml="urn:oasis:names:tc:SAML:2.0:assertion" IssueInstant="2011-03-19T08:30:00Z" ID="foo" Version="2.0">' SAML-AAA-Assertion += '<saml:Issuer>urn:mace:incommon:osu.edu</saml:Issuer>' SAML-AAA-Assertion += '<saml:AttributeStatement>' SAML-AAA-Assertion += '<saml:Attribute NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:uri" Name="urn:oid:1.3.6.1.4.1.5923.1.1.1.7"><saml:AttributeValue>moonshot</saml:AttributeValue></saml:Attribute>' SAML-AAA-Assertion += '</saml:AttributeStatement>' SAML-AAA-Assertion += '</saml:Assertion>' } } }
In
/etc/freeradius/sites-enabled/abfab-tr-idp
, find thepost-auth
section. At the top, insert onto its own line the following:if (&request:GSS-Acceptor-Service-Name != 'trustidentity') && (&request:Realm == 'YOUR_REALM_HERE') { moonshot_saml }
You can adjust where you want to call the policy that inserts the Moonshot policy, as long as it is called in thepost-auth
section.- If you use non-TLS connections for Moonshot, you may wish to repeat Step 2 in
/etc/freeradius/sites-enabled/default
. - Restart FreeRADIUS.
