Case 4: Password Services and Directory Requests

A company has enabled Password Services for their user store. The company uses the following formula to continue estimating the number of requests the Policy Server sends to the user directory to service the authentication load:

authentication_load * 1 = requests_for_authentication

• authentication_load

  Represents the number of daily authentications for the application.

  Note: One (1) is a constant. Tracking user login details requires one write to the user directory for each authentication.

• requests_for_authentication

  Represents the number of user directory requests that the authentication load creates.

Result: 88,000 * 1 = 88,000 requests.

The company uses this estimate to determine the total number of user directory requests required to service the daily authentication load.
