[Samba] Howto set/reset/reaad computer account password with samba-4.9.x examples?

[Oliver Rath]

Hi list,

I want to perform a domain join of a computer to a given machine account
with reusing it, not overwriting. For this I think, it is the right way
(for a unattend.xml) to use the <machinePassword> described here:
https://docs.microsoft.com/en-us/windows-hardware/customize/desktop/unattend/microsoft-windows-unattendedjoin-identification#child-elements

in the new feature list of samba 4.9.x is written "The 'samba-tool
computer' command allow manipulation of computer accounts including
creating a new computer and resetting the password. This allows an
'offline join' of a member server or workstation to the Samba AD domain."

Unfortunatly I dont find any example for

  * resetting the password (the "setpassword" from user command doesnt
    work, maybe simply --password?)
  * creating a computer with a given machine password (maybe simply
    --password,too ?)
  * reading the machine password from AD (there i found some old variant
    which didnt work, tested with Win81-clients)
  * perform an offline join with a previously given/read-from-ad machine
    password

Is this possible, some examples anywhere?

Tfh!
