Ticket #48892 - Wrong result code display in audit-failure log
    
    Bug Description: Although a command line returns an error code 32,
    audit-failure-log logs -1.
    
    Fix Description: In the backend code, if a target entry does not
    exist, -1 was internally set to ldap_result_code.  The code was
    interpreted to LDAP_NO_SUCH_OBJECT in the frontend before returning
    to the client.  But the audit-failure-log logged the internal code.
    This patch fixes it.
