/*
* Functions to glue a bunch of other backends into a single tree.
* All of the glued backends must share a common suffix. E.g., you
* can glue o=foo and ou=bar,o=foo but you can't glue o=foo and o=bar.
*
* This uses the backend structures and routines extensively, but is
* not an actual backend of its own. To use it you must add a "subordinate"
* keyword to the configuration of other backends. Subordinates will
* automatically be connected to their parent backend.
*
* The purpose of these functions is to allow you to split a single database
* into pieces (for load balancing purposes, whatever) but still be able
* to treat it as a single database after it's been split. As such, each
* of the glued backends should have identical rootdn and rootpw.
*
* If you need more elaborate configuration, you probably should be using
* back-meta instead.
* -- Howard Chu
