Changes to Databases that use mTLS Authentication (MOS Doc ID 2911553.1)

 Description:

 DigiCert retired the Organizational Unit (OU) field for all public TLS/SSL certificates to comply with industry standards as of August 2022 per their announcement: https://knowledge.digicert.com/alerts/ou-removal.html. This means that the public TLS/SSL certificates issued by DigiCert will not have the OU field anymore.

To avoid any disruptions to existing client connections, Autonomous Database will support doing DN matching based on the host property of your connection string. If you are using mTLS authentication, you must use an Oracle client library version that supports this new approach and download your wallet zip file with the new mTLS connection strings on or after January 10th, 2023 and before March 6th, 2023.
