eWeek for 31Oct05 had a pretty interesting eWeek Labs review of the open source portal tool Liferay Portal 3.6.1 that you might be interested in if you need to setup a prototype portal server for a demo or for small workgroup just getting started. This is a J2EE based portal that will support identity management via LDAP or Active Directory.  Other links mentioned in the podcast:
