You can use Kerberos authentication to connect to Oracle databases by placing the required configuration files on the Secure Agent machine. You can also use Kerberos authentication to connect to SSL-enabled Oracle databases.
When you configure Kerberos authentication to connect to Oracle, consider the following guidelines:
You can't use the Hosted Agent or serverless runtime environment.
Ensure that the Secure Agent and database server that you use are registered in the KDC server.
You can't add more than one KDC to a krb5.conf file.
You can't generate a credential cache file for more than one Kerberos principal user.
