"Admin rights" is an over-simplification here.
The relevant principle is called separation of duty.
For adding the computer account and to set the temporary computer
password you need admin rights in the OU within the domain.
For joining the machine with its computer account you need (temporary)
administrative access to the machine and the temporary computer password.
But it should not be required to enter the password of the OU admin on
the machine to be joined!
I think one can do this with msktutil --set-samba-secret for renewing
host keytab and Samba's secret.tdb.
I recently wrote an ansible role with which an OU admin (has TGT on
ansible controller) pre-creates / resets the computer account and the
machine is joined with msktutil and temporary computer password in one play.
