Access Management tools can be very useful but I think the entry cost and lack of documentation have prevented its widespread adoption. This is going to change with OpenSource projects like OpenSSO.
For example, Dennis just added two simple sets of diagrams describing SSO and Access Control and Authentication. More detailed information on OpenSSO is availalable at the project site including: articles on OpenSSO, Project News (with many useful links), the FAQ Center, and the Documentation Top Page.
