Summary:

The code changes in this pull request focus on improving the security and reliability of the persistence layer across various Jans applications, including SAML, SCIM, Auth Server, and Configurator. The key changes include:

1. Removal of Hardcoded Passwords: The code now retrieves database passwords (Couchbase, SQL) from secure sources, such as environment variables or secrets management systems, instead of hardcoding them in the codebase. This reduces the risk of sensitive credential exposure.

2. Secure Configuration Management: The applications use environment variables and configuration managers to handle various settings, including persistence types, SSL/TLS certificates, and logging configurations. This approach promotes a more secure and maintainable configuration management process.

3. Persistence Layer Simplification: The changes remove support for certain persistence backends (e.g., Couchbase, SQL) in some applications, reducing the overall attack surface and complexity of the applications.

4. Improved Logging and Monitoring: The code includes updates to the logging configuration, allowing for better control and visibility of the applications' security-related events.

5. Secure LDIF File Handling: The applications import LDIF files for configuration and client data. Ensuring the integrity and security of these LDIF files is important to prevent the introduction of malicious data or unauthorized modifications.

Overall, the changes in this pull request appear to be focused on improving the security and maintainability of the Jans applications, particularly in the areas of credential management, configuration, and persistence layer setup. These changes are in line with application security best practices and should help strengthen the overall security posture of the applications.
