Authasas Advanced Authentication® can be scaled to domains of virtually any size.  Deploying multiple instances of the Authenticore® Server provides multi-master clustering, automatic load balancing, hot-swapping, scalability and fault-tolerance.  

Authasas provides powerful intelligent server search algorithms enabling client components to find and establish communication with the nearest Authenticore® Server available.  If no authentication server was found in the scope of the site, the process of searching for a server continues within the domain of the organization, or the Authasas client will revert to local cache.
