[cifs-protocol] What happened to SamLogon validation level 4?

[Andrew Bartlett]

In MS-NRPC 2.2.1.4.17 NETLOGON_VALIDATION_INFO_CLASS it states:

   The NETLOGON_VALIDATION_INFO_CLASS enumeration selects the type of logon information
  block being used.
    typedef enum _NETLOGON_VALIDATION_INFO_CLASS
    {
       NetlogonValidationUasInfo = 1,
       NetlogonValidationSamInfo = 2,
       NetlogonValidationSamInfo2 = 3,
       NetlogonValidationGenericInfo2 = 5,
       NetlogonValidationSamInfo4 = 6
    } NETLOGON_VALIDATION_INFO_CLASS;

However, level 4 is missing.  It appears however in the wireshark
dissector (and therefore in our IDL).  What is the history here?

Also, what restrictions are there on choice of validation level for the
different logon levels available into a SamLogon* call?

Thanks,

Andrew Bartlett
