Case 5: Total Directory Requests for Authentication

A company uses the individual totals from each use case to determine the total number of requests the Policy Server sends to the user store to service the authentication load:

• 176,000 requests to identify 88,000 unique users and their credentials
• 22,000 requests to determine if the OnAuth SiteMinder policy applies to those users
• 22,000 requests to return the common name attribute upon authentication
• 88,000 requests for the password policy

Result: 176,000 + 22,000 + 22,000 + 88,000 = 322,080 requests

The company uses this result and the results based on the authorization load to estimate the sustained rate at which the user store must service Policy Server requests.
