Beat can correct me if I'm wrong, but if you can get a version that allows login through Joomla, it should work with CB login also, since CB login takes the place of Joomla login module.
There is this:
mambowiki
. This is mediawiki for joomla. However I have read that it will not use the CB login.
I can't remember where I read that right now, I'll have a look again.
