samba - Feb 2022 - DSDB Audit of User Creation/Deletion on Samba DC

I run Samba 4.13 on an Ubuntu 20.04 LTS server as an Active Directory Domain
Controller, and one of my compliance responsibilities is to log and audit user
creation, deletion, and modification (group member changes).  I thought I could
accomplish this with:

log level = 1 dsdb_json_audit:5 dsdb_password_json_audit:5
dsdb_group_json_audit:5 dsdb_transaction_json_audit:5

in smb.conf, and indeed, I do receive a lot of dsdbChange and groupChange
notifications in log.samba.  Further testing of this though leads me to believe
that I either have something missing or user creation is not logged as a dsdb
change.

My question is whether or not that is true, in which case how do I log user
creation, and if it isn?t true, what am I missing in my configuration?

Thanks for any insights.

How do you create the users?  If you use command-line tools locally,
then local access as root won't be logged to log.samba, it will be
logged to the terminal (this wasn't made a priority to address as the
root user could just turn off the logs anyway).

Perhaps your sudo logging might capture these, or use root less and do
remote operations to add users.
