There are different methods used to set up single sign on authentication. One method is where you allow the computer to store the user’s name and password, after it is initially authenticated at first log in. From that point on, anytime the user initiates a resource which requires authentication, the computer automatically performs the request in the background, without requiring the user for any further input.
Grouping Is another Method Used with Single Sign on Authentication
Another type of method which can be used with single sign on authentication is called grouping. Grouping is where organizations will take applications and resources and group them based on the type of security required. Low level security resources and applications can be included with a single sign on when they pose little risk to the organization. Such items can include word processing applications, shared network storage drives and network printers.
