When PK-INIT is performed, check that the buffer is as expected and
contains the correct NT hash.
The PK-INIT tests now pass against Windows Server 2019.

To run these tests standalone, you will need the certificate and private
key of the Certificate Authority. These can be specified together in the
same file with the environment variable CA_CERT, or the private key may
be specified in its own file with CA_PRIVATE_KEY.
If either of these files are encrypted, you can specify the password in
the environment variable CA_PASS.
These tests create a new certificate for the user account, signed with
the private key of the Certificate Authority. We negotiate the reply key
with either of the public-key and Diffie-Hellman PK-INIT variants, and
use the reply key to decrypt the enc-part in the response. We also check
that the KDC’s signatures are valid.
Most of the failures with the Heimdal KDC are due to the wrong nonce
being returned in the reply compared to Windows, which issue is simple
enough to correct.
An example command line for manual testing against Windows:
SMB_CONF_PATH=ad_dc.conf KRB5_CONFIG=krb5.conf SERVICE_USERNAME=win2k19-dc.example.com ADMIN_USERNAME=Administrator ADMIN_PASSWORD=locDCpass ADMIN_KVNO=1 FOR_USER=Administrator USERNAME=Administrator PASSWORD=locDCpass DC_SERVER=win2k19-dc.example.com SERVER=win2k19-dc.example.com DOMAIN=example REALM=example.com PYTHONPATH=bin/python STRICT_CHECKING=1 FAST_SUPPORT=1 CLAIMS_SUPPORT=1 COMPOUND_ID_SUPPORT=1 TKT_SIG_SUPPORT=1 FULL_SIG_SUPPORT=1 GNUTLS_PBKDF2_SUPPORT=1 EXPECT_PAC=1 EXPECT_EXTRA_PAC_BUFFERS=1 CHECK_CNAME=1 CHECK_PADATA=1 KADMIN_IS_TGS=0 FORCED_RC4=1 DEFAULT_ETYPES=36 CA_CERT=./win2k19-ca.pfx CA_PASS=1234 python3 python/samba/tests/krb5/pkinit_tests.py
To set up windows for this I first installed an Certificate Authority with an Enterprise CA.
Then I exported the private key and certificate of the CA:
1. go into the Certification Authority snap-in for the relevant computer,
2. right-clicking the CA
3. clicking ‘All Tasks’ → ‘Back up CA...’
4. and exporting the private key and CA certificate.
(I downloaded the resulting file via smbclient).
After setting up an Enterprise CA, I also needed to edit the domain
controller GPO to enable auto-enrollment, otherwise Windows would
refuse to accept as legitimate any certificates provided by the client.
That can be done by first enabling the policy:
‘Computer Configuration/Policies/Windows Settings/Security Settings/Public Key Policies/Certificate Services Client — Auto-Enrollment’,
and then ticking both ‘Renew expired certificates…’ and ‘Update certificates…’)

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.

We don't have any documentation about this yet, but tests against
a Windows Server 2022 patched with KB5028166 revealed that
the response for query_level=2 is exactly the same as
for querey_level=1.
Until we know the reason for query_level=2 we won't
use it as client nor support it in the server, but
we want ndrdump to work.

There are multiple places we make this assumption. For example, in
source3/lib/tldap.c, we have this line
if (ld->msgid == 2147483647) {
where ld->msgid is an int. And in librpc/idl/security.idl we have
several lines like:
const int SEC_MASK_GENERIC = 0xF0000000;
In lib/replace/inet_pton.c and inet_ntop.c we have
/*
* WARNING: Don't even consider trying to compile this on a system where
* sizeof(int) < 4. sizeof(int) > 4 is fine; all the world's not a VAX.
*/
but no attempt to enforce that as far as I can see, until now.
