           Summary: RpcBindingSetAuthInfo(Ex) fails with
                    RPC_C_AUTHN_GSS_NEGOTIATE
           Product: Wine
           Version: CVS/GIT
          Platform: Other
        OS/Version: other
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: winesku at googlemail.com


RpcBindingSetAuthInfo(Ex) fails  with RPC_S_UNKNOWN_AUTHN_SERVICE if
RPC_C_AUTHN_GSS_NEGOTIATE is specified. While this looks correct at first
glance, because WINE's secur32.dll currently has no Negotiate provider, but
instead only an NTLM provider, it is not what applications expect. Since
Windows 2000, RPC clients that call RpcBindingSetAuthInfo(Ex) can at least
expect that this call succeeds with the selection of NTLM, even in non-domain
environments. Therefore WINE's RpcBindingSetAuthInfo(Ex) should make a fallback
to RPC_C_AUTHN_WINNT if RPC_C_AUTHN_GSS_NEGOTIATE is requested by the caller
but only NTLM is available. After all, by specifying RPC_C_AUTHN_GSS_NEGOTIATE,
the client indicated that NTLM is sufficient.
