Ticket 365 - passwords in clear text in the audit log
Bug Description: after changing a user password, an additional modify is added to the
mods: "unhashed#user#password: <clear text password>"
e.g. PSEUDO_ATTR_UNHASHEDUSERPASSWORD
Fix Description: Added new config param "nsslapd-audit-logging-hide-unhashed-pw".
The default is "on". When "on" that single modify op is skipped from
the audit logging.
