Thanks for the question.  As samba-tool user setpassword operates
locally on the sam.ldb, the logging is done in the tool - typically to
stderr.

We realise this isn't ideal.  The cop-out is that someone with local
root access can just edit the database at even lower levels anyway.

Remote password changes should be logged, say if you use -H to specify
the ldap server and the administrator password.

I hope this helps,
