This is the Samba 4 version of bug 6100
Microsoft Open Protocol Document MS-NRPC
NetrLogonDummyRoutine1, section 126.96.36.199.5.
For win7 this is renamed NetrLogonGetCapabilities – opnum 21,
see section 188.8.131.52.10
- Function call to test for a man-in-the-middle attack,
this was first implemented in win2k.
- If Samba supported the end-point, but not the method,
and returned “status not implemented”, then the response
is secure and we would downgrade to prior behavior.
In short, Samba needs to be returning STATUS_NOT_IMPLEMENTED
rather than returning an unauthenticated RPC layer error.
Should be fixed with commit 94abbead1b76e7aafee8c59233b096a3f03b35c8
Ok, then mark it as "FIXED".
