org.apache.catalina.authenticator.package.html Maven / Gradle / Ivy
This package contains Authenticator implementations for the
various supported authentication methods (BASIC, DIGEST, and FORM). In
addition, there is a convenience base class,
AuthenticatorBase, for customized Authenticator
implementations.
If you are using the standard context configuration class
(org.apache.catalina.startup.ContextConfig) to configure the
Authenticator associated with a particular context, you can register the Java
class to be used for each possible authentication method by modifying the
following Properties file:
src/share/org/apache/catalina/startup/Authenticators.properties
Each of the standard implementations extends a common base class
(AuthenticatorBase), which is configured by setting the
following JavaBeans properties (with default values in square brackets):
- cache - Should we cache authenticated Principals (thus avoiding
per-request lookups in our underyling
Realm) if this request
is part of an HTTP session? [true]
- debug - Debugging detail level for this component. [0]
The standard authentication methods that are currently provided include:
- BasicAuthenticator - Implements HTTP BASIC authentication, as
described in RFC 2617.
- DigestAuthenticator - Implements HTTP DIGEST authentication, as
described in RFC 2617.
- FormAuthenticator - Implements FORM-BASED authentication, as
described in the Servlet API Specification, version 2.2.
