I checked in the FlexWiki security framework last night. This completes the initial tasks of getting a plugable architecture for storing the user and permission information. The only Data Provider that is available right now is a SimpleDataProvider. This data provider is designed to be simple to deploy but is limited in it's performance capabilities. Check out the FlexWikiSecurityProject for more details. Next up I have to start plugging the security into the FlexWiki web.
