Wren:IDM is a community‐developed identity management system with a flexible data model, multiple extension points and scripting support, including JavaScript and Groovy. It can connect to and manage a wide range of systems through the Identity Connector Framework (Wren:ICF).

Wren:IDM is one of the projects in the Wren Security Suite, a community initiative that adopted open‐source projects formerly developed by ForgeRock, which has its own roots in Sun Microsystems’ products.

Wren:IDM itself is focused on identity management processes and it also provides a powerful framework for implementing IAG and a portion of IAM processes as well. Although the project is based on OpenIDM code, it is not affiliated with ForgeRock in any way. It is based on the very latest code available under a CDDL license (not‐yet‐released OpenIDM 5.x).

The features of Wren:IDM include:

  • A complete platform for building IDM and IG solutions using the concepts described below – roles, mappings, synchronizations, workflows, policies, etc.
  • ICF Connector Servers – services that allow connectors to be run outside of the IDM itself. Useful when a connector needs a specific client environment to talk to the integrated system. Also facilitates security. .NET and Java Connector Servers are available.
  • Administration GUI – an interface for making changes to data models and configuration using a point‐and‐click interface rather than Wren:IDM's REST interface.
  • Self‐service GUI – an interface for end‐users to update their profile information, passwords, and preferences.

Both the Administration GUI and Self‐Service GUI are web‐based, single‐page applications that can be turned off in deployments that do not desire to use them [1].
