ldapscripts package shipped in Debian is slightly modified to work out of the box. If you have libnss-ldap installed and configured, ldapscripts will use configuration from libnss-ldap.conf. More details could be found in comments inside /etc/ldapscripts/ldapscripts.conf If you have any problems with ldapscripts' utilities, first look on /var/log/ldapscripts.log where all details, warnings and errors goes.
