Hi Andreas,
I'm glad it worked out! Thank you for the excellent documentation suggestions. I will follow up on those.
Please reach out to our DocHelp alias if you find anything else we can help with.

Ok, so the mac key **doesn't get truncated** to 32 bytes, only the enc key
does. MS-SAMR doesn't document that!
I followed the RFC MS-SAMR links
https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Ftools.ietf.org%2Fid%2Fdraft-mcgrew-aead-aes-cbc-hmac-sha2-03.html%23rfc.section.5.4&data=05%7C01%7Cjeffm%40microsoft.com%7Cf45828600c95467f13f008da649ff2d5%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637932935523400281%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000%7C%7C%7C&sdata=ChVyXmZDn6zBgDw26qokrCauRueSl1TO2bPd4n77FJ4%3D&reserved=0
and here the mac key gets truncated to 32 bytes.
With a 64 byte mac key I was able to generate the auth_data correctly! Now I'm
able to change the password on Windows :-)
$ ./bin/rpcclient ncacn_np:earth.milkyway.site -U'Administrator%Secret007!' -c
'setuserinfo2 bob 31 Pa$$w0rd at 3'
[..]
rpc_api_pipe: host earth.milkyway.site returned 4 bytes.
samr_SetUserInfo2: struct samr_SetUserInfo2
out: struct samr_SetUserInfo2
result : NT_STATUS_OK
$ ./bin/rpcclient ncacn_np:earth.milkyway.site -U'bob%Pa$$w0rd at 3'
rpcclient $> getusername
Account Name: bob, Authority Name: EARTH
Summary
=======
2.2.1.18 AEAD-AES-256-CBC-HMAC-SHA512 Constants
a) You should document that an uint8_t should be used to store the
version_byte
b) You should document that an uint8_t should be used to store the
version_byte_len
c) For SAM_AES256_ENC_KEY_STRING_LENGTH you should clarify that this includes
the terminating null byte of the string!
d) For SAM_AES256_MAC_KEY_STRING_LENGTH you should clarify that this includes
the terminating null byte of the string!
2.2.6.32 SAMPR_ENCRYPTED_PASSWORD_AES
A reference to MS-DTYP would be useful e.g. for ULONG and ULONGLONG
3.2.2.4 AES Cipher Usage
a) Document that for the enc_key only the first 32bytes get used
b) Document that the mac_key is not truncated, the complete 64bytes are used
c) Mention that you mighte need to add PKCS#7 padding to the plaintext to
match the AES block size.
That should make it clearer how to implement it correctly :-)
Thank you very much for your assistance!
Best regards
