Are you stating that only one assignment of tdb can be defined? I use
the rid backend for the domains that are hosted on another server but
wasn't sure whether or not multiple tdb backend assignments were
allowed. Although I've never tried it, the man page does not appear to
state that tdb cannot be used for multiple backends. But I'm reading
the man page for 4.7.0rc5 which may be different.
