It seems that since sometime around February no new "autocreate" events are logged to the database on WMF wikis. I'm not sure if this is a CentralAuth bug (it seems CentralAuthHooks.php hasn't been touched for a while), but I couldn't find anything in User.php either... maybe also a WMF-only bug, I didn't test the latest SVN version.
This was a deliberate change. See bug 27287 for details. *** This bug has been marked as a duplicate of bug 27287 ***
