SCIM

Penn State's Open Source JavaEE implementation of the Simple Cross-domain Identity Management (SCIM) version 2.0 specification (RFC7642, RFC7643 and RFC7644). This project is constructing a SCIM framework using first-principles from the released specifications. Much of the code is being adapted from Penn State's "Friends of Penn State" (FPS) implementation.

History

In June of 2013, we embarked on replacing the FPS system that now serves over 3MM non-privileged accounts. Our goals for this rewrite were to eliminate the redundant persistence (data was stored in both an RDBMS and LDAP) as well as to replace the ancient and inefficient XML-based APIs with an industry standard API. The SCIM specification was, at the time still almost two years away from being released, but even the early versions of the specification showed the promise of a modern API.

The FPS implementation of SCIM has been in production for over two years and as stated above is managing over 3MM identities. The system is adding almost 400K identities per year and uses LDAP for persistence.

Goals

Now that the specification has been ratified, we're writing a generic implementation from first-principles with the goal of forming a community around the core features but allowing customization via ResourceType "providers". The modules that implement the specification require Java SE8. The server implementations require Java EE7.

The goals for the project are as follows:

  • Declarative creation of new ResourceTypes and Extensions.
  • Example implementations of the server with various persistence paradigms.
  • Dynamic generation of the Schema and ResourceType end-points.
  • A suite of tools to allow the creation of SCIM resources that can then be verified against the appropriate schemas.
  • A set of verification tests to ensure the project meets the specification and to allow inter-operability testing.

Tutorials and demonstrations

Example code

Examples of the project's declarative syntax are shown below. The first example shows how a SCIM resource is declared:

@Data
@EqualsAndHashCode(callSuper = true)
@ScimResourceType(
  id = ScimUser.RESOURCE_NAME,
  name = ScimUser.RESOURCE_NAME,
  schema = ScimUser.SCHEMA_URI,
  description = "Top level ScimUser",
  endpoint = "/Users"
)
@XmlRootElement(name = ScimUser.RESOURCE_NAME)
@XmlAccessorType(XmlAccessType.FIELD)
public class ScimUser extends ScimResource {

  public static final String RESOURCE_NAME = "User";
  public static final String SCHEMA_URI = "urn:ietf:params:scim:schemas:core:2.0:User";

  @ScimAttribute(
    description="A Boolean value indicating the User's administrative status.",
    type=Type.BOOLEAN
  )
  
  @XmlElement(name = "active")
  Boolean active = true;

  @ScimAttribute(
    type = Type.COMPLEX,
    description="A physical mailing address for this User, as described in (address Element). Canonical Type Values of work, home, and other. The value attribute is a complex type with the following sub-attributes."
  )
  @XmlElement(name = "addresses")
  List<Address> addresses;

In the example above, annotations are used at the class level and member level to declare a new SCIM resource and its attributes respectively. The example below shows the equivalent declaration for a resource Extension:

@XmlRootElement
@XmlAccessorType(XmlAccessType.NONE)
@ScimExtensionType(
  required = false,
  name = "EnterpriseUser",
  id = EnterpriseExtension.URN,
  description = "Attributes commonly used in representing users that belong to, or act on behalf of, a business or enterprise."
)
@Data
public class EnterpriseExtension implements ScimExtension {

  public static final String URN = "urn:ietf:params:scim:schemas:extension:enterprise:2.0:User";

    @XmlType
    @XmlAccessorType(XmlAccessType.NONE)
    @Data
    public static class Manager {

      @ScimAttribute(
        description = "The \"id\" of the SCIM resource representing the user's manager.  RECOMMENDED."
      )
  
      @XmlElement
      private String value;

      @ScimAttribute(
        description = "The URI of the SCIM resource representing the User's manager.  RECOMMENDED."
      )
      
      @XmlElement
      private String $ref;

This example shows how an extension is declared at the class level, but also provides an example of how complex SCIM types can be simply defined as suitably annotated inner classes.

Implementations are fully customizable without altering the core server code. The example below shows how the implementation for a provider is declared:

public class InMemoryUserService implements Provider<ScimUser> {

Implementing the provider interface allows the customization of create, retrieve, update and delete methods (as well as find). Customization is flexible - if your system implements soft deletes, create a delete method that simply sets a flag and alter the find and retrieve methods to only return "undeleted" resources.

  @Inject
  EndpointUtil endpointUtil;
  .....
  .....
  URL groupEndpoint = endpointUtil.getEndpoint(ScimGroup.class);
  URL userEndpoint = endpointUtil.getEndpoint(ScimUser.class);

With reference type returns developers may need to access the base endpoints used to execute the SCIM request.
The example above illustrates injecting an endpointUtil class, which is a helper class that provides that specific information. If this identity provider does not provide a a provisioner for the endpoint requested null is returned.
