PURPOSE: A method for the simple certification reinforcing security is provided to enhance the security to a simple bind operation without introducing a Kerberos infra in order to enhance the stability and reliability for the information managed by a directory server. CONSTITUTION: A binding packet is received from a directory user(309). A Hash value is obtained by extracting a user ID from the binding packet, bringing a user's password managed at the inside, and applying a Hash function to the password(311).
