This repo intended to create SCIM librabry compartible with Azure pseudo-SCIM implementation. You need to create two WS for that: /User and /Group

SCIM 2 SDK

SCIM, or System for Cross-domain Identity Management, is an IETF standard that defines an extensible schema mechanism and REST API for managing users and other identity data. SCIM is used by a variety of vendors — including Facebook, Salesforce, Microsoft, Cisco, Sailpoint, and UnboundID — for a variety of purposes, including user provisioning, directory services, attribute exchange, and more.

The UnboundID SCIM 2 SDK for Java provides a powerful and flexible set of APIs for interacting with SCIM service providers and resources. Use it to build applications and servers that interoperate with SCIM servers such as the UnboundID Data Broker.

The SCIM 2 SDK consists of the following components:

Component name	What it is	Who needs it
scim2-sdk-client	The SCIM 2 client API.	SCIM client developers.
scim2-ubid-extensions	Model classes representing UnboundID extensions to the SCIM standard. This component is subject to API changes and should be considered experimental.	SCIM client developers using features specific to UnboundID servers.
scim2-sdk-server	Classes for use by SCIM 2 service providers.	SCIM service provider implementers.
scim2-sdk-common	Shared model, exception, and utility classes.	Included as a transitive dependency of all of the above.

How to get it

The SCIM 2 SDK is available from Maven Central and can be included in your product like any other Maven dependency. Check Maven Central for the latest available version of SCIM 2 SDK dependencies.

For general-purpose clients:

<dependency>
  <groupId>com.unboundid.product.scim2</groupId>
  <artifactId>scim2-sdk-client</artifactId>
  <version>VERSION</version>
</dependency>

For clients using UnboundID-specific features:

<dependency>
  <groupId>com.unboundid.product.scim2</groupId>
  <artifactId>scim2-ubid-extensions</artifactId>
  <version>VERSION</version>
</dependency>

You may also download SCIM 2 SDK builds from the Releases page.

If you're looking for a Java SDK for SCIM 1.1, you can find it here.

How to use it

The SCIM 2 SDK requires Java 7 or greater.

The primary point of entry for a client is the ScimService class, which represents a SCIM service provider, such as the UnboundID Data Broker. This class acts as a wrapper for a JAX-RS client instance, providing methods for building and making requests.

Other classes provide facilities for selecting attributes by path, building query filters, and working with JSON documents. SCIM resources returned from a service provider can either be represented as POJOs or using an API based on the Jackson tree model.

        .page(1, 5)
        .attributes("name")
        .invoke(UserResource.class);
