OpenSSO adds Active Directory support to its Configurator
By superpat on Feb 23, 2007
Anyway - Dennis just blogged that the OpenSSO WAR Configurator now supports Active Directory as a datastore. Explanation: You install OpenSSO by just deploying the WAR file into a suitable container - just about any servlet container will do, though some work better than others. When you first go to OpenSSO's URL, it detects that it has not yet been configured and shows the Configurator page.
OpenSSO can use a variety of repositories for its configuration data (separately from the choice of user repository or authentication method). We have supported flat files and Sun Java System Directory Server for some time now; we just added support for Active Directory.
So - if you're curious, go download OpenSSO and give it a whirl.
