@Override
        public String getName() { return "ssl-auth-max-token-validity"; }
The property representing the amount of time that a temporary
authentication token for SSL/TLS authentication may remain valid, in
minutes. This token is used to represent the user's asserted identity
after it has been verified by the SSL termination service. This interval
must be long enough to allow for network delays in receiving the token,
but short enough that unused tokens do not consume unnecessary server
resources and cannot potentially be guessed while the token is still
valid. These tokens are 256-bit secure random values.
