derby.authentication.provider

Function

Specifies the authentication provider for Derby user authentication.

Legal values include:

LDAP
An external LDAP directory service.
A complete Java class name
A user-defined class that provides user authentication.
BUILTIN
Derby's simple internal user authentication repository.

Important: Derby's BUILTIN authentication mechanism is suitable only for development and testing purposes. It is strongly recommended that production systems rely on LDAP or a user-defined class for authentication. It is also strongly recommended that production systems protect network connections with SSL/TLS.

When using an external authentication service provider (LDAP), you must also set:

derby.authentication.server

When using LDAP, you can set other LDAP-specific properties. See also:

Alternatively, you can write your own class to provide a different external authentication service. This class must implement the public interface org.apache.derby.authentication.UserAuthenticator and throw exceptions of the type java.sql.SQLException where appropriate. Using a user-defined class makes Derby adaptable to various naming and directory services. For example, the class could allow Derby to hook up to an existing user authentication service that uses any of the standard directory and naming service providers to JNDI.

To enable any Derby user authentication, you must set the derby.connection.requireAuthentication property to true.

For more information about user authentication, see the Derby Developer's Guide.
