A simple PingDirectory server deployment is illustrated in the following figure.
- A client request is initiated.
- The client connection policy processes the client request.
- The client connection policy contains a subtree view, which defines the portion of the directory information tree (DIT) available to clients and determines if the DIT is available.
- After the PingDirectory server determines that the DIT is available, it passes the request to the request processor, which defines the logic for processing the request.
- The request processor passes the request to a load-balancing algorithm, which determines the server in a set of servers responsible for handling the request.
- The request is passed to the LDAP external server. Note:
The LDAP external server contains properties that define the server’s location in a topology and the health checks used to determine if the server is functioning properly.
This information can be used by the load-balancing algorithm for determining how to route requests.
