After much delay, the Nexus Crowd plugin has reached it first public release. If you've built the plugin from source in the past, please read the installation instructions as the configuration model has changed dramatically. Configruation is now done through a configuration file in the sonatype-work/nexus/conf directory, rather than via Plexus. This will make it easier to upgrade in the future as well as support a UI-based configuration (vote for NEXUS-1410 if this is important for you).
Thanks to everyone who helped me out over the past few months.
