SAML 2 NameID Attribute Definition

This attribute definition creates an attribute whose values are SAML 2 NameIDs. This attribute definition always uses the SP's entity ID as the NameID SPNameQualifier.

1. Create the Definition

The definition is created with the element <resolver:AttributeDefinition xsi:type="SAML2NameID" xmlns="urn:mace:shibboleth:2.0:resolver:ad"> with the following required attributes:

• id: A unique identifier used within the IdP's resolver and filter to reference this definition.

and an optional attribute:

• nameIdFormat: Becomes the Format attribute on the created SAML 2 <NameID> element. Defaults to urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified.
• nameIdQualifier: Becomes the NameQualifier attribute on the created SAML 2 <NameID> element. Defaults to the IdP's entity ID.
• sourceAttributeID - the ID of the attribute, from the dependency connectors, used to construct this attribute (default value: ID of this attribute)
• dependencyOnly: A boolean flag that indicates the attribute produced by this definition is used only by other resolver components and should never be released from the resolver. Defaults to false.

<resolver:AttributeDefinition xsi:type="SAML2NameID" xmlns="urn:mace:shibboleth:2.0:resolver:ad"
                              id="UNIQUE_ID"
                              sourceAttributeID="ATTRIBUTE_ID">

     <!-- Remaining configuration from the next step goes here -->

</resolver:AttributeDefinition>

2. Define Dependencies

You must express, as a dependency, the attribute definition or data connector that produces the source attribute. Dependencies are declared using a <resolver:Dependency> with a ref attribute whose value is the unique ID of the dependent attribute definition or the data connector.

<resolver:AttributeDefinition xsi:type="SAML2NameID" xmlns="urn:mace:shibboleth:2.0:resolver:ad"
                              id="UNIQUE_ID"
                              sourceAttributeID="ATTRIBUTE_ID">

     <resolver:Dependency ref="DEFINITION_ID_1" />

</resolver:AttributeDefinition>
