eZ publish

We recently built a nice intranet with eZ Publish including LDAP integration. The biggest deficiency is that implementing a wiki is not out of the box. The biggest problem was that the rollout was so quick that the client went crazy pushing content and tweaking long before we were ready to leave. We supported multiple users/groups editing various parts with multiple users/groups checking the edits. Not heroic, but certainly useful workflows.

While eZ Publish might be a great CMS, it is absolutely unsuitable for project management and intranet workflows. User rather dotProject for such tasks.
