WebRT, though it's really only suited to a rather small setup unless you
tweak it by hand some (we're mostly using it to track software development
bug reports, as opposed to task management).

Speaking of, and not for, my employer (the .sig is personal)

There've been a lot of improvements made to RT since it was
  called "WebRT" -- including a total rewrite, which is now in
  beta. http://www.fsck.com/projects/rt/ has info.
