Authentication Notification Message

A Lightweight Directory Access Protocol (LDAP) server device for storing a first attribute value corresponding to a latest registered time for user login to a network function device, and a second attribute value corresponding to a time when the user was latest authenticated, the LDAP server device comprising processing circuitry and memory operatively coupled to the processing circuitry, the processing circuitry and memory being configured to:

• receive, from an LDAP client device, an authentication notification message after the user has been successfully authenticated, the authentication notification message indicating a successful authentication of the user and is performed by the network function device, wherein the authentication notification message comprises a timestamp corresponding to a time associated with the successful authentication of the user;
• and
• update the second attribute value to a value that corresponds to or is the time associated with the successful authentication of the user.

A Lightweight Directory Access Protocol (LDAP) client device comprising processing circuitry and memory operatively coupled to the processing circuitry, the processing circuitry and memory being configured to:

• send, to an LDAP server device, an authentication notification message after a user has been successfully authenticated, wherein the authentication notification message notifies that the user has been successfully authenticated by a network function device, wherein the authentication notification message comprises a timestamp corresponding to a time associated with the successful authentication of the user.
