  It's not cached unless you configure the "persist_dir".  See the eap module configuration for more information.

  Just set "persist_dir", and the attributes in the Access-Accept should be cached.

  The caching has been re-done in v3.1, so that it's a lot cleaner and easier to understand.  It's just too hard to fix v3.0 at this point.
