What is HLA, LLA/ LLAWP within the Advanced Authentication (SiteMinder) Webagent?



The framework agents break the existing Web Agent’s access control functionality into logical blocks, called ‘managers’ e.g: Challenge Manager, Resource Manager. Managers are assigned specific tasks and are controlled by a single High-Level Agent (HLA) manager that implements the logic of SiteMinder access control.


The High Level Agent orchestrates the complete flow of servicing a request, from receiving the request to finally authorizing access to the requested resource.


The Low Level Agent Worker Process (LLAWP) implements the Agent-to-Policy Server DoManagement polling mechanism as well as writing log messages to the physical log medium and collating health data for the SiteMinder One-View Monitor. The Low Level Agent Worker Process uses shared memory to communicate between clients, and to facilitate logging and caching.
