Understanding LDAP and Its Role in User Management and Security

LDAP, or Lightweight Directory Access Protocol, is a robust infrastructure for user and security management. It centralizes user profiles to streamline authentication across multiple ECSs (Enhanced Communication Systems) within a network. With its flexible design, LDAP can efficiently handle user authentication based on aliases or IP addresses, utilize both static and online information for endpoint location, and keep the server updated with endpoint data. The protocol's design, as outlined by the IETF, enables effective authorization and enhances overall security management for organizations.

  2. LDAP: Lightweight Directory Access Protocol • LDAP serves as a flexible, scalable user- and security-management infrastructure to store and manage user profiles and to serve as the basis for site-wide user authentication and security • Allows for one central database to be updated for authentication via multiple ECSs on the network • LDAP is an IETF standard defined by the Accessing and Indexing Directories (ASID) working group.

  3. LDAP – Main Features today • Authentication • When an endpoint registers to the ECS, it is authenticated according to its alias/es and or IP address. • Location of Endpoint (using static/online info) • If ECS cannot find the destination in its zone, it searches the static info or the online info directory • Update • The ECS updates the LDAP server with information about online endpoints, such as aliases, call signaling address and RAS address. • Retrieve neighbor GK list • The ECS reads the neighbor list from the LDAP server every fixed time

  4. LDAP – Tree Structure

  5. New LDAP Schema Based on Draft H.350.x recommendations (February 2003) • Authentication • At registration to the ECS, the endpoint will be authenticated according to its H.235 sender Id and password • Fixed aliases from LDAP • Successful registration will utilize aliases as defined in LDAP and NOT in the endpoint • Authorization • Different service level groups will be utilized for authorization of the call by the ECS at the ARQ stage
