The LDAP Tool Box project provides a set of LDAP-related applications, administrative tools, and other utilities. They have just released version 3.2 of their slapd-cli tools (formerly called openldap-initscript), which provide a set of command-line tools for OpenLDAP. The primary change in this release appears to be a fix to an issue in the check_sync tool in which it could not handle a base64-encoded olcsyncrepl attribute.
