How do I prevent CMU database users from resetting their passwords locally.

Hello all

Database 19.13.0 on Linux RHAT 7.

After successfully configuring Centrally Managed Users (CMU) with Microsoft Active Directory, I have come into a situation where some users have reset their password in the database and not via our AD integrated security tool.

When that happens the users are now being authenticated locally instead via the AD.

How do I prevent users from resetting their password locally

for example using alter user identified by xxxxxxx account unlock. from happening and force them to reset their password via our AD?

Thanks
