This bug is created as a clone of upstream ticket:
389 should use ldap_set_option(ld, LDAP_OPT_X_SASL_NOCANON, LDAP_OPT_ON) for outgoing ldap connections. This option should also be configurable via a configuration attribute, with the value of "on" by default.
[root@dhcp201-126 export]# ldapsearch -p 389 -h localhost -D "cn=Directory Manager" -w Secret123 -LLL -b "cn=config" | grep nsslapd-connection-nocanon
