HSQLDB supports various authentication methods for securing database access. The authentication methods available in HSQLDB include:
File-Based Authentication:
* HSQLDB supports authentication based on username-password pairs stored in a file called sa.password.
* User credentials are hashed and stored in this file.
* This authentication method is suitable for basic authentication needs and small-scale deployments.
Custom Authentication :
* HSQLDB allows developers to implement custom authentication mechanisms by implementing the org.hsqldb.auth.AuthFunction interface.
* With custom authentication, developers have full control over how user credentials are validated, allowing integration with external authentication systems or custom authentication logic.
LDAP Authentication :
* HSQLDB supports authentication using Lightweight Directory Access Protocol (LDAP) servers.
* User authentication is performed against an LDAP directory, allowing centralized user management and authentication.
* This authentication method is suitable for organizations with existing LDAP infrastructure and centralized user directories.
Kerberos Authentication :
* HSQLDB supports authentication using the Kerberos network authentication protocol.
* Kerberos authentication provides secure authentication between clients and servers in a network environment.
* This authentication method is suitable for environments requiring strong security measures and centralized authentication services.
Mixed Mode Authentication :
* HSQLDB supports mixed-mode authentication, allowing a combination of different authentication methods to be used concurrently.
* For example, you can configure HSQLDB to use LDAP authentication for some users and file-based authentication for others, based on their roles or access requirements.
