The Federal E-Authentication profile specifies the SAML 1.0 artifact profile in conjunction with some restrictions on assertion content. ShibOnedotThree supports this profile.

Configure an IdP for E-Authentication Use

The set-up process assumes that a complete InQueue installation and testing has been performed and you have a functional Shibboleth IdP. If not, complete that section first.

Add a virtual host in apache that uses the proper eAuth cert/key for SSL (in ssl.conf).
Create SAML2 metadata for each AA (sample below).
Add a metadata provider element (in idp.xml) that points to eAuth metadata. (<MetadataProvider/> in the sample below)
Add a protocol handler for the eAuth SSO handler (in idp.xml) (<ProtocolHandler/> in the sample below).
Add an extra location for the artifact lookup handler that maps to eAuth SSL endpoint (in idp.xml) (<ProtocolHandler implementation="edu.internet2.middleware.shibboleth.idp.provider.SAMLv1_1ArtifactQueryHandler"/> in the sample below).
Add servlet mappings for the eAuth SSO handler and the eAuth location for the artifact lookup handler (in web.xml).
Add a name mapping that uses Subject DNs (in idp.xml) (<NameMapping/> in the sample below).
Add a relying party element w/defaultTarget (this should be equal to the "TARGET" query parameter used in the artifact redirect) for each AA (in idp.xml) (<RelyingParty/> in the sample below)
Adjust the attribute resolver configuration to include a commonName attribute. (in resolver.xml) (don't forget the eAuth namespace).

Example resolver.xml snippet:

<SimpleAttributeDefinition id="commonName" sourceName="commonName" namespace="http://eauthentication.gsa.gov/federated/attribute">
	<DataConnectorDependency requires="echo"/>
</SimpleAttributeDefinition>

Adjust the attribute release polices to release the commonName attribute (in arp.site.xml).
Configure the SAML 1->1.1 filter (in web.xml).

Example web.xml snippet:

<filter>
	<filter-name>SAML 1 to 1.1 Conversion Filter</filter-name>
	<filter-class>edu.internet2.middleware.shibboleth.utils.SAML1_0to1_1ConversionFilter</filter-class>
</filter>
<filter-mapping>
	<filter-name>SAML 1 to 1.1 Conversion Filter</filter-name>
	<url-pattern>/eAuthArt</url-pattern>
</filter-mapping>

Notes

The Sun AA implementation does not seem to work with the SSLVerifyClient optional_no_ca Apache directive. To get around this, you must configure client-auth and create an appropriate trust bundle.

Example SAML 2.0 metadata for E-Authentication use: eAuth-sites.xml

Example idp.xml file for E-Authentication use: idp.xml

Configure an SP for E-Authentication Use

The set-up process assumes that a complete InQueue installation and testing has been performed and you have a functional Shibboleth SP. If not, complete that section first.

`shibboleth.xml` Configuration

The ShibbolethApplication being configured for EAuthenticationDeployment must have an AssertionConsumerService element inside its Sessions element set up as below:

<md:AssertionConsumerService xmlns:samlp="urn:oasis:names:tc:SAML:1.0:protocol"
	Location="/SAML/Artifact" index="1"
	Binding="urn:oasis:names:tc:SAML:1.0:profiles:artifact-01"
	samlp:MinorVersion="0">

The index value can be anything as long as it's unique within the set of elements. The distinction with a normal artifact profile endpoint is the additional namespace-qualified MinorVersion attribute. This attribute defaults to 1, indicating support for SAML 1.1 in most Shibboleth configurations. Set it to 0 to enable SAML 1.0 support. This works for POST or artifact, but EAuthenticationDeployment requires the use of artifact.

Additional settings that may be helpful...

strictValidity and propagateErrors in your MemorySessionCache or MySQLSessionCache element may need to be "false" to prevent premature expiration of the attributes included in the short-lived EAuthnAssertion, and in some cases the lack of an AttributeAuthority offered by the IdentityProvider to refresh them

AttributeAcceptancePolicy Configuration

A starting policy file is attached: eauth-AAP.xml

CredentialServiceProvider MetaData Configuration

Supplying MetaData for an EAuth CredentialServiceProvider is essentially the same as for any other Shibboleth IdentityProvider, except that:

The EntityDescriptor element's entityID attribute is set to the CSP's approved value for Assertion Issuer
The IDPSSODescriptor element's protocolSupportEnumeration attribute must contain "urn:oasis:names:tc:SAML:1.0:protocol" to indicate support for SAML 1.0
The SingleSignOnService element's Binding attribute can be set to urn:mace:shibboleth:1.0:profiles:EAuth (currently not used, but identifies the redirection protocol that might be used to invoke the CSP)
There may not be an AttributeAuthorityDescriptor included
