Overview
The JAAS (Java Authentication and Authorization Service) is a desktop authentication mechanism in Java that has been commonly misappropriated as a server-side technology. A variety of "login module" plugins exist for different password-based technologies. Support is provided for using JAAS as a back-end for the password authentication login flow.
General Configuration
Configuring JAAS as a back-end requires that the right import is active in conf/authn/password-authn-config.xml:
| Code Block | ||||
|---|---|---|---|---|
| ||||
<import resource="jaas-authn-config.xml" /> |
All others should The other imports must be commented or removed.

General Configuration
Use conf/A few beans are defined in authn/jaas-authn-config.xml to configure this back-end . Bean definitions are as follows:
...
by identifying the JAAS configuration file and JAAS application name(s) to use.
JAAS Configuration
JAAS has its own configuration format (see here). By default, the configuration used is called "ShibUserPassAuth". This can be changed using the shibboleth.authn.JAAS.LoginConfigNames, or turned into a list of more than one configuration, with each one tried in series until a success. This is equivalent to the JAAS keyword "sufficient". Using separate configurations allows errors to be isolated per-module instead of masked by generic JAAS exceptions.
Reference
Beans
The beans defined in authn/jaas-authn-config.xml follow:
Bean ID | Type | Default | Function |
|---|---|---|---|
| JAASConfig | String | %{idp.home}/conf/authn/jaas.config | Defines a Spring Resource containing the JAAS config. Normally this just points to a file in the filesystem |
...
| shibboleth.authn.JAAS.JAASConfigURI |
...
JAAS Configuration
...
| java.net.URI | JAASConfig.URI | Defines the URI object containing the JAAS configuration | |
| shibboleth.authn.JAAS.LoginConfigNames |
...
| java,util.List<String> | [ "ShibUserPassAuth" ] | List of JAAS application configuration names to use |
V2 Compatibility
JAAS configuration is independent of the IdP and is therefore identical with the use of JAAS in the V2 UsernamePassword handler. By default this configuration is placed in authn/jaas.config and the legacy-matching "ShibUserPassAuth" login configuration name is used (though this can be changed).
Unlike V2, the JAAS configuration is not placed into a global system property that would apply to the container as a whole; it is private to the IdP application.
