Return Value

string

A string that contains the final status of the method. The return value can be one of the values that are listed in WMI Provider Return Strings, or one of the following values.

Name Description

success

The password change histories that have end times that are earlier than the specified time were successfully deleted from the server.

access-denied

The user who is running this method is not a member of the Forefront Identity Manager Synchronization Service (FIM Synchronization Service) security groups. Verify that the user is a member of one of these groups.

invalid-date-parameter

The specified date is in the wrong format, or password change histories do not exist for this date. Verify that the specified date is in the correct format.

Remarks

FIM Synchronization Service uses the password change history log to determine whether the number of password changes that are requested in a 24-hour period exceeds the number that is specified in the management agent properties. When you successfully run this method, the history log is cleared and a new 24-hour period is started for the maximum number of password changes.

To clear the password change history log, run the ClearPasswordQueue Method before you run this method. If you run the ClearPasswordQueue Method after you run this method, any pending password change logs are then moved to the history log.

It is a best practice to periodically archive and clear the password target history. A large number of target history objects can detract from the performance of the ClearPasswordHistory Method.
