This is important as Windows clients with KB5028166 seem to
call netr_LogonGetCapabilities with query_level=2 after
a call with query_level=1.
An unpatched Windows Server returns DCERPC_NCA_S_FAULT_INVALID_TAG
for query_level values other than 1.
While Samba tries to return NT_STATUS_NOT_SUPPORTED, but
later fails to marshall the response, which results
in DCERPC_FAULT_BAD_STUB_DATA instead.
Because we don't have any documentation for level 2 yet,
we just try to behave like an unpatched server and
generate DCERPC_NCA_S_FAULT_INVALID_TAG instead of
DCERPC_FAULT_BAD_STUB_DATA.
Which allows patched Windows clients to keep working
against a Samba DC.

The domain-local groups that are added to the PAC of a service ticket
