386 * Unsupported! Use at your own risk!
387 * -- Howard Chu, Symas Corp. 2003.
389 * Instead of a ldbm-style dn2id database, we use a hierarchical one. Each
390 * entry in this database is a struct diskNode, keyed by entryID and with
391 * the data containing the RDN and entryID of the node's children. We use
392 * a B-Tree with sorted duplicates to store all the children of a node under
393 * the same key. Also, the first item under the key contains the entry's own
394 * rdn and the ID of the node's parent, to allow bottom-up tree traversal as
395 * well as top-down. To keep this info first in the list, the high bit of all
396 * subsequent nrdnlen's is always set. This means we can only accomodate
397 * RDNs up to length 32767, but that's fine since full DNs are already
398 * restricted to 8192.
400 * The diskNode is a variable length structure. This definition is not
401 * directly usable for in-memory manipulation.
