ProxiedRequesterEntityAttributeExactMatchConfiguration

Namespace: urn:mace:shibboleth:2.0:afp
Schema: http://shibboleth.net/schema/idp/shibboleth-afp.xsd

Overview

The ProxiedRequesterEntityAttributeExactMatch type is a PolicyRule that returns true if the SAML metadata for a proxied requester contains <mdattr:EntityAttribute> extension data matching the supplied parameterization.

Specifying the attributeNameFormat attribute in the rule will constrain the rule to match only against the underlying XML representation of the extension data. Omitting it will permit the rule to match against the data mapped from the XML via the AttributeRegistryConfiguration, which increases efficiency.

The notion of a “proxied requester” varies by profile/protocol/use case, and generally does not involve metadata. This rule can be applied in cases where metadata may be available (and is actually being accessed).

Reference

Name	Type	Required?	Default	Description

Name	Type	Required?	Default	Description
attributeName	String	Y		The SAML Attribute `Name` to match against
attributeValue	String	Y		The string value to match against
attributeNameFormat	URI			The SAML Attribute `NameFormat` to test against (if not specified, then matching is solely based on the `Name`)
ignoreUnmappedEntityAttributes	Boolean		false	When true, this constrains the rule to ignore the underlying XML and match solely against the data mapped via the AttributeRegistryConfiguration

Example

The above policy would match the tags in the metadata below:

<PolicyRequirementRule xsi:type="ProxiedRequesterEntityAttributeExactMatch"
	attributeName="urn:mace:example.org:policy" attributeValue="urn:mace:example.org:policy:ABCD1234" />
