3.3.5.1.9 MS-RAS-Correlation-ID

If the rasCorrelationId parameter of the SendRadiusAccessRequest abstract interface (section 3.3.4.1) is set to the NULL GUID (all bytes are set to zero), this attribute MUST NOT be set. Otherwise, the attribute-specific value is obtained by serializing the rasCorrelationId parameter to the format described in section 2.2.1.20.
