SCIM is an Abbreviation of System for Cross-domain Identity Management.

The SCIM protocol is a client-server protocol.

A SCIM Client initiates a communication to a SCIM Service Provider which then responds to the SCIM Client.

A given entity could be either a SCIM Client or a SCIM Service Provider for any given transaction. But the same entity could be both a SCIM Client AND a SCIM Service Provider depending on who initiates the transaction.

Most of the information provided is on SCIM 2.0.

The SCIM specification suite seeks to build upon experience with existing schemas and deployments, placing specific emphasis on simplicity of development and integration, while applying existing authentication, authorization, and privacy models.

SCIM intent is to reduce the cost and complexity of user management operations by providing a common user schema and extension model, as well as binding documents to provide patterns for exchanging this schema using standard protocols. In essence: make it fast, cheap, and easy to move users in to, out of, and around the cloud.

SCIM data can be encoded as a SCIM object in JSON or XML encoding both defined within the specification. SCIM 2.0 specifies the use of JSON.

SCIM: Why It’s More Important, and More Simple than you think#

Why SCIM 1.1 will not work#

From an Organizational Entity perspective, SCIM 1.1 does not support HTTP PATCH but only HTTP PUT. So adding a single SCIM User to a SCIM Group requires replacing the entire SCIM Group. When there might be 10,000 users this is not a reasonable expectation.
