18 * Functions to glue a bunch of other backends into a single tree.
19 * All of the glued backends must share a common suffix. E.g., you
20 * can glue o=foo and ou=bar,o=foo but you can't glue o=foo and o=bar.
22 * The purpose of these functions is to allow you to split a single database
23 * into pieces (for load balancing purposes, whatever) but still be able
24 * to treat it as a single database after it's been split. As such, each
25 * of the glued backends should have identical rootdn.
