How to block Oracle's operating system authentication on different operating systems

On the Windows system > If you do not want the user through the operating system authentication mode login, you can modify the Sqlnet.ora file, put sqlnet. Authentication_services=nts the front plus # comment out.

On Linux Systems > If you do not want users to log on by operating system authentication, you can create a Sqlnet.ora file, plus
Sqlnet. The authentication_services is set to None or NTS, which are screened for operating system authentication based on Oracle password authentication.
