Experimental Patch for Ticket#2015061621000357

Reportedly some Huawei storage devices don't pass a NtVer attribute for
CLDAP netlogon.

[MS-ADTS] Section 6.3.3.2 "Domain Controller Response to an LDAP Ping" says
that the server should respond normally in this case by sending a
NETLOGON_SAM_LOGON_RESPONSE_NT40 structure as reponse.
