SCIM 2.0
System for Cross-domain Identity Management: a REST+JSON standard for provisioning users and groups across domains. An identity source (the SCIM client — an IdP or HR system) pushes the joiner-mover-leaver lifecycle into an application (the SCIM service provider) through a fixed resource model exposed at /Users and /Groups, so accounts are created, updated, and deactivated automatically instead of by hand.
