We're looking for a sharepoint replacement.
We're looking for an open source application that runs on apache2. It should basically be a document store with comments. Integration with AD to administer permissions. We've been looking for a few days, but the google fu of multiple people have failed.
We've tried Alfresco, but it runs very slowly for us (tomcat).
We're looking into django-cms but it seems like the wrong sort of thing (built for something different)
