ILM 2007 Design Concepts Document Set

There is a great set of ILM Design Concept documents available here.  Essentially they are Microsoft's collective response and official design recommendations for key scenarios they often see from customers.  Heavy reading, but great knowledge.

From the overview:

Design Concepts for Reference Attributes
This document explains how reference attributes are processed by ILM 2007 for direct attribute mapping scenarios and provides a conceptual explanation of a custom solution for advanced mapped reference attributes. It also includes design recommendations for both direct and advanced mapped attributes.

Design Concepts for Correlating Digital Identities
This document discusses considerations for mapping attributes across different identities and configuring joins based on your business requirements. It introduces the concept of Correlation ID and explains how you can deploy a Correlation ID to establish strong object relationships in your identity integration solution.

Design Concepts for Implementing IFunctions
This document introduces the concept of object-level identity functions (IFunctions) in an identity integration scenario, discusses possible implementation options, and also provides implementation recommendations.

Design Concepts for Implementing Reverse Joins
This document discusses some of the common reverse join implementation approaches for synchronizing identity objects in ILM 2007. It provides two recommended solutions for implementing reverse joins- reverse joins based on Transient management agents and reverse joins based on Auxiliary management agents.

Design Concepts for Provisioning Based on Group Membership
This document discusses the design and the implementation of an identity integration solution that supports provisioning decisions based on Active Directory group membership.
In these documents, you will find detailed discussions of specific challenges that are often encountered during the design of ILM solutions. These documents present some of the most common design issues that are discussed in newsgroups and in e-mail discussion groups.
