#  testwalk.pl - Walks through Records Matching a Given Filter
#  Author:  Clayton Donley, Motorola, <donley@cig.mot.com>
#
#  Demonstration of OO Style LDAP Calls Using Net::LDAPapi
#
#  Similar to ldapwalk2.pl, only it uses the OO versions of the synchronous
#  functions to retrieve a hash containing the matching entries.
#
#  Usage:  testwalk.pl FILTER
#  Example:  testwalk.pl "sn=Donley"
#
