Overview
The SAML V2.0 General Purpose Subject Identifier (subject-id) is a user identifier attribute defined in the SAML v2.0 Subject Identifier Attributes Profile. It is a long-lived, non-reassignable, omnidirectional identifier suitable for use as a globally-unique external key. Its value for a given subject is independent of the relying party to whom it is given.
