Hello Andrew,
   I have reviewed the network capture and it clearly shows what you are 
describing. The reason that the msprc fault occurred in Frame 1695 is that 
there is no Authverifier information in the LSARPC:LsarLookupSids3 Request in 
Frame 1694. Looking at a successful LSARPC:LsarLookupSids3 Request in a 
different capture I see that the Authverifier field is present. This field 
contains the RPC_C_AUTHN_NETLOGON and the RPC_C_AUTHN_LEVEL_INTEGRITY 
information. I am theorizing that the Authverifier field is missing in your 
trace because there was not a RPC Bind exchange prior to this request.

My source code investigation indicates that if the  Authverifier field is 
present that the server will behave as described in MS-LSAT 3.1.4.9. When the 
Authverifier field is absent then it will lead to an msrpc Fault of access 
denied.

Is it the intention of your test to determine what would happen when a 
LSARPC:LsarLookupSids3 Request is made when there is no Authverifier 
information present?

Thanks
John

PS: I looked into your question about running your test suites. I found out 
that some of the Interop folks have an instance of your Samba 4 running as a DC 
and that some of the SMBTorture tests have been run against it. More 
information in this area should be forthcoming.

Samba4's RPC-LSA test shows this behaviour (capture attached)

Are we any closer to you being able to run the tests yourself?
