NameIDFormatFilter

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

Overview

A filter of type NameIDFormat adds SAML <md:NameIDFormat> elements to metadata in order to drive software behavior (primarily Name Identifier format selection).

Sequences of string-valued <Format> elements are supplied as filter content. When a child element such as <Entity> or <ConditionRef> or <ConditionScript> evaluates to true, the formats are applied to all the recognized format-supporting roles of the corresponding entities. The filter does not have the capability to limit the roles to which formats will be attached.

Filter order is important!

This filter changes the content of the metadata and so a filter of type NameIDFormat should appear after any https://shibboleth.atlassian.net/wiki/spaces/IDP4/pages/1265631654 in the overall MetadataProvider.

 

Position the NameIDFormat filter for efficiency

Deliberately position a NameIDFormat filter in the overall sequence of filters for optimal efficiency. In particular, a filter of type NameIDFormat should appear after the https://shibboleth.atlassian.net/wiki/spaces/IDP4/pages/1265631646 since the latter effectively removes entities from the input.

Description

<Format>

Content is name identifier format which is added to all the applicable roles of the entities which match any of the following <Entity> or <ConditionRef> elements.

<Entity>

The textual content is an EntityID. All preceding formats are added to applicable roles of the matching entity.

<ConditionRef>      

The textual content is the Bean ID of a Predicate<EntityDescriptor>. All preceding formats are added to the roles of the entities for which this returns true.

<ConditionScript>

The content of this element is an inline or local script resource that implements Predicate<EntityDescriptor>. All preceding formats are added to the entities for which this returns true.

Examples

 The example will add the "persistent" format to the first entity, and both the "persistent" and "email" formats to the second.

Add NameIDFormat elements to metadata
1 2 3 4 5 6 <MetadataFilter xsi:type="NameIDFormat"> <Format>urn:oasis:names:tc:SAML:2.0:nameid-format:persistent</Format> <Entity>https://sp1.example.org</Entity> <Format>urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress</Format> <Entity>https://sp2.example.org</Entity> </MetadataFilter>

The following example is similar, but the specification of the entities to apply the formats to is handled with inline scripts. Obviously these scripts aren't particularly useful but they demonstrate the syntax.

Use of scripts
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 <MetadataFilter xsi:type="NameIDFormat"> <Format>urn:oasis:names:tc:SAML:2.0:nameid-format:persistent</Format> <ConditionScript> <Script> <![CDATA[ input.getEntityID().equals("https://sp1.example.org"); ]]> </Script> </ConditionScript> <Format>urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress</Format> <ConditionScript> <Script> <![CDATA[ input.getEntityID().equals("https://sp2.example.org"); ]]> </Script> </ConditionScript> </MetadataFilter>
