211 Having slapd configuration files and ldap databases in /var/lib/openldap
212 readable by anyone is a SECURITY ISSUE, especially since a file stores
213 admin password in PLAIN TEXT. That's why mode 640 and root:ldap ownership
214 were used. Owner is root, so only root can modify the file, and group is
215 ldap, so that the group which owns slapd daemon could read but not modify
216 the file in case of a security breach.

762 is a set of Lightweight Basic Encoding Rules routines. These
763 routines are used by the LDAP library routines to encode and decode
764 LDAP protocol elements using the (slightly simplified) Basic

766 by an LDAP application program except in the handling of controls
767 and extended operations.
