# Usage: Add something like this to slapd.conf:
#
#	database	perl
#	suffix		"o=AnyOrg,c=US"
#	perlModulePath	/directory/containing/this/module
#	perlModule	SampleLDAP
#
# See the slapd-perl(5) manual page for details.
#
# This demo module keeps an in-memory hash {"DN" => "LDIF entry", ...}
# built in sub add{} & co.  The data is lost when slapd shuts down.
