To connect to PostgreSQL databases with Kerberos authentication, place the required Kerberos configuration files on the Secure Agent machine.
When you configure Kerberos authentication to connect to PostgreSQL, 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.
When you user Kerberos authentication on Windows, ensure that the user account that starts the Secure Agent service is available in the PostgreSQL database. You don't need to enter your credentials to access PostgreSQL.
