Summary:

The code changes in this pull request cover a wide range of modifications across multiple files in the Janssen Project. The changes primarily focus on improving the handling of user data, including user attributes, authentication, and SCIM (System for Cross-domain Identity Management) functionality. Overall, the changes do not introduce any obvious security concerns, but there are a few areas that should be reviewed to ensure the ongoing security and integrity of the application.

Files Changed:

1. Database Configuration and Schema Changes:

   • The changes in the pgsql-config.md and mysql-config.md files update the database configuration, including password hashing, connection pool management, and data mapping. These changes generally follow good security practices.
   • The jans-sql.properties file updates the MySQL-specific configuration, including the use of simple JSON handling, which should be reviewed to ensure it does not introduce any security vulnerabilities.
   • The jans-schema.json and jans-schema-mappings.json files update the Janssen schema, including the renaming of the jansAddress attribute. These changes are mostly routine maintenance tasks.

2. SCIM Functionality Changes:

   • The changes in the custom_scim_handler.java and custom_scim_handler.py files focus on the handling of SCIM search results, including the removal of sensitive user data (e.g., addresses) from the response. These changes are security-conscious.
   • The Scim2UserService.java file includes updates to the handling of user attributes, such as email addresses and extended attributes. These changes improve the overall functionality and security of the SCIM implementation.

3. User Authentication and Attribute Management:

   • The changes in the UserAuthenticator.java and UserAuthenticatorService.java files focus on improving the handling of user authenticators, including the implementation of hashCode() and equals() methods. These changes help ensure the proper management of user authentication data.
   • The SimpleUser.java file includes updates to the user attribute management functionality, such as the addition of a removeAttributeValue() method. These changes can be beneficial for maintaining data integrity and user privacy.

4. Test and Sample Code Changes:

   • The changes in the various test and sample code files, such as DatabaseTest.php, SqlEntryManagerSample.java, and SpannerSample.java, are mostly routine maintenance tasks and do not introduce any significant security concerns.

Overall, the code changes in this pull request appear to be focused on improving the functionality and maintainability of the Janssen Project, with a few security-conscious updates. While there are no obvious security vulnerabilities introduced, it's important to review the changes in the context of the entire application and ensure that the application's security practices are robust and up-to-date.
