** This module implements an abstraction of an interface to an LDAP address
** book.  There's no reason to reinvent the wheel, so we simply run ldapsearch
** as a child process, and read its output.  ldapsearch is run indirectly, via
** a stub shell script that can be customized on a given system.  The template
** for the stub shell script is provided.
**
** There's a small library here that can be used to maintain a configuration
** file listing available address books that can be contacted.  The format
** of each line in this library is simply:
**
** name<tab>host<tab>port<tab>suffix<tab>binddn<tab>bindpw
**
** Functions are provided to add and remove names from this configuration
** file easily.  The above is parsed into the following structure:
