Specifies the number of minutes, during a log on session, a user is prompted for identity verification. If a value other than zero is specified, the user is prompted after the specified minutes have been reached to re-enter their password. If a password is not re-entered within the amount of time that was specified in the Verify timeout minutes field, then the session is disconnected.
A zero (0) indicates there is no expiration and is the default. You can specify up to a maximum value of 525600 minutes (equivalent to one year).
