An SP affiliation is a SAML 2.0 specification that permits a group of service providers to make use of the same persistent name identifier for account linking (see Account linking).

This may be of use when multiple service providers share a business relationship in which users need services from each affiliated provider. By agreement among the affiliation members, the same pseudonym can be used to populate the SAML_SUBJECT of assertions sent to all of the SP partners contained in this affiliation.

Note:

Each connection in the affiliation must be configured to use the same IdP adapter instance for generating account links (see Managing authentication source mappings).
