Overview

Identified by type="Delegation", this AttributeExtractor allows content from within a SAML DelegationRestriction condition to be extracted and passed to an application as an attribute. This allows for finer-grained control over delegation at an SP. The information that's eventually expressed in string form to the application is controlled by a formatter XML attribute that can reference specific content from within the <del:Delegate> elements in the condition.

Reference

An expression containing any number of "substitution" variables starting with a '$' character that reference information from the <del:Delegate> element.

The set of formatter variables consists of:

  • Information derived from the corresponding content of the <saml2:NameID> element found within the <del:Delegate> element. Typically delegates are SAML entities that are named by entityIDs and only the $Name property is relevant.

    • $Name

    • $Format

    • $NameQualifier

    • $SPNameQualifier

    • $SPProvidedID

  • A SAML confirmation method URI that identifies how the delegate confirmed its identity to the IdP.

    • $ConfirmationMethod

  • The time at which the delegate confirmed its identity to the IdP.

    • $DelegationInstant
