Hi Andreas,
The server is returning STATUS_INVALID_PARAMETER because it appears the 'Cipher' is missing from the encrypted password structure. I see the AuthData and Salt, and cbCipher = 0x210, and I see PBKDF2Iterations = 0x20000, but no Cipher. What are you intending to send?

Thank you for the traces, Andreas!
I am analyzing them and sill let you know what I find.

I've created a time trace and a network capture and uploaded it to the workspace.
./bin/rpcclient ncacn_np:earth.milkyway.site -U'Administrator%Secret007!' -c
'setuserinfo2 bob 31 Pa$$w0rd at 2'
result was NT_STATUS_INVALID_PARAMETER
