The SAML V2.0 Pairwise Subject Identifier (pairwise-id) is a user identifier attribute defined in the SAML v2.0 Subject Identifier Attributes Profile. It is a long-lived, non-reassignable, unidirectional identifier suitable for use as a unique external key specific to a particular relying party. Its value for a given subject depends upon the relying party to whom it is given, thus preventing unrelated systems from using it as a basis for correlation.
