* 368: Allow SASL Connections to Periodically Re-Authenticate</a>. The session
* length is the minimum of the configured value and any session length implied
* by the credential presented during authentication. The lifetime defined by
* the credential, in terms of milliseconds since the epoch, is available via a
* negotiated property on the SASL Server instance, and that value can be
* converted to a session length by subtracting the time at which authentication
* occurred. This variable defines the negotiated property key that is used to
* communicate the credential lifetime in milliseconds since the epoch.
