25;;; Commentary:
26
27;; This package provides basic functionality to perform searches on LDAP
c69b943f
PJ
28;; servers. It requires a command line utility generally named
29;; `ldapsearch' to actually perform the searches. That program can be
7970b229
GM
30;; found in all LDAP developer kits such as:
31;; - UM-LDAP 3.3 (http://www.umich.edu/~dirsvcs/ldap/)
32;; - OpenLDAP (http://www.openldap.org/)
