/**
* An {@link AuthenticationProvider} implementation that retrieves user details from a JAAS login configuration.
*
* <p>This <code>AuthenticationProvider</code> is capable of validating {@link
* org.springframework.security.authentication.UsernamePasswordAuthenticationToken} requests contain the correct username and
* password.</p>
* <p>This implementation is backed by a <a
* href="http://java.sun.com/j2se/1.5.0/docs/guide/security/jaas/JAASRefGuide.html">JAAS</a> configuration that is provided by
* a subclass's implementation of {@link #createLoginContext(CallbackHandler)}.
*
* <p>When using JAAS login modules as the authentication source, sometimes the
* <a href="http://java.sun.com/j2se/1.5.0/docs/api/javax/security/auth/login/LoginContext.html">LoginContext</a> will
* require <i>CallbackHandler</i>s. The AbstractJaasAuthenticationProvider uses an internal
* <a href="http://java.sun.com/j2se/1.5.0/docs/api/javax/security/auth/callback/CallbackHandler.html">CallbackHandler
* </a> to wrap the {@link JaasAuthenticationCallbackHandler}s configured in the ApplicationContext.
* When the LoginContext calls the internal CallbackHandler, control is passed to each
* {@link JaasAuthenticationCallbackHandler} for each Callback passed.
* </p>
* <p>{@link JaasAuthenticationCallbackHandler}s are passed to the AbstractJaasAuthenticationProvider through the {@link
* #setCallbackHandlers(org.springframework.security.authentication.jaas.JaasAuthenticationCallbackHandler[]) callbackHandlers}
* property.
* <pre>
* &lt;property name="callbackHandlers"&gt;
* &lt;list&gt;
* &lt;bean class="org.springframework.security.authentication.jaas.TestCallbackHandler"/&gt;
* &lt;bean class="{@link JaasNameCallbackHandler org.springframework.security.authentication.jaas.JaasNameCallbackHandler}"/&gt;
* &lt;bean class="{@link JaasPasswordCallbackHandler org.springframework.security.authentication.jaas.JaasPasswordCallbackHandler}"/&gt;
* &lt;/list&gt;
* &lt;/property&gt;
* </pre>
* </p>
* <p>
* After calling LoginContext.login(), the AbstractJaasAuthenticationProvider will retrieve the returned Principals
* from the Subject (LoginContext.getSubject().getPrincipals). Each returned principal is then passed to the
* configured {@link AuthorityGranter}s. An AuthorityGranter is a mapping between a returned Principal, and a role
* name. If an AuthorityGranter wishes to grant an Authorization a role, it returns that role name from it's {@link
* AuthorityGranter#grant(java.security.Principal)} method. The returned role will be applied to the Authorization
* object as a {@link GrantedAuthority}.</p>
* <p>AuthorityGranters are configured in spring xml as follows...
* <pre>
* &lt;property name="authorityGranters"&gt;
* &lt;list&gt;
* &lt;bean class="org.springframework.security.authentication.jaas.TestAuthorityGranter"/&gt;
* &lt;/list&gt;
* &lt;/property&gt;
* </pre>

<title>Overview</title>
</info>
<para>Spring Security provides a package able to delegate authentication requests to the
Java Authentication and Authorization Service (JAAS). This package is discussed in
detail below.</para>
</section>
<section xml:id="jaas-abstractjaasauthenticationprovider">
<info>
<title>AbstractJaasAuthenticationProvider</title>
</info>
<para>The <classname>AbstractJaasAuthenticationProvider</classname> is the basis for the
provided JAAS <interfacename>AuthenticationProvider</interfacename> implementations. Subclasses
must implement a method that creates the <classname>LoginContext</classname>. The
<classname>AbstractJaasAuthenticationProvider</classname> has a number of dependencies that can
be injected into it that are discussed below.</para>
<para>Central to JAAS operation are login configuration files. To learn more about JAAS
login configuration files, consult the JAAS reference documentation available from Sun
Microsystems. We expect you to have a basic understanding of JAAS and its login
configuration file syntax in order to understand this section.</para>
<section xml:id="jaas-callbackhandler">
<info>
<title xml:id="jaas-callback-handler">JAAS CallbackHandler</title>
</info>
<para>Most JAAS <literal>LoginModule</literal>s require a callback of some sort. These
callbacks are usually used to obtain the username and password from the user.</para>
<para>In a Spring Security deployment, Spring Security is responsible for this user
interaction (via the authentication mechanism). Thus, by the time the authentication
request is delegated through to JAAS, Spring Security's authentication mechanism
will already have fully-populated an <interfacename>Authentication</interfacename>
object containing all the information required by the JAAS
<literal>LoginModule</literal>.</para>
<para>Therefore, the JAAS package for Spring Security provides two default callback
handlers, <literal>JaasNameCallbackHandler</literal> and
<literal>JaasPasswordCallbackHandler</literal>. Each of these callback handlers
implement <literal>JaasAuthenticationCallbackHandler</literal>. In most cases these
callback handlers can simply be used without understanding the internal
mechanics.</para>
<para>For those needing full control over the callback behavior, internally
<classname>AbstractJaasAuthenticationProvider</classname> wraps these
<literal>JaasAuthenticationCallbackHandler</literal>s with an
<literal>InternalCallbackHandler</literal>. The
<literal>InternalCallbackHandler</literal> is the class that actually implements
JAAS’ normal <literal>CallbackHandler</literal> interface. Any time that the JAAS
<literal>LoginModule</literal> is used, it is passed a list of application context
configured <literal>InternalCallbackHandler</literal>s. If the
<literal>LoginModule</literal> requests a callback against the
<literal>InternalCallbackHandler</literal>s, the callback is in-turn passed to the
<literal>JaasAuthenticationCallbackHandler</literal>s being wrapped.</para>
</section>
<section xml:id="jaas-authoritygranter">
<info>
<title xml:id="jaas-authority-granter">JAAS AuthorityGranter</title>
</info>
<para>JAAS works with principals. Even "roles" are represented as principals in JAAS.
Spring Security, on the other hand, works with
<interfacename>Authentication</interfacename> objects. Each
<interfacename>Authentication</interfacename> object contains a single principal,
and multiple <interfacename>GrantedAuthority</interfacename>s. To facilitate
mapping between these different concepts, Spring Security's JAAS package includes an
<literal>AuthorityGranter</literal> interface.</para>
<para>An <literal>AuthorityGranter</literal> is responsible for inspecting a JAAS
principal and returning a set of <literal>String</literal>s, representing the
authorities assigned to the principal. For each returned authority string, the
<classname>AbstractJaasAuthenticationProvider</classname> creates a
<classname>JaasGrantedAuthority</classname> (which implements Spring Security’s
<interfacename>GrantedAuthority</interfacename> interface) containing the authority
string and the JAAS principal that the
<interfacename>AuthorityGranter</interfacename> was passed. The
<classname>AbstractJaasAuthenticationProvider</classname> obtains the JAAS principals by
firstly successfully authenticating the user’s credentials using the JAAS
<literal>LoginModule</literal>, and then accessing the
<literal>LoginContext</literal> it returns. A call to
<literal>LoginContext.getSubject().getPrincipals()</literal> is made, with each
resulting principal passed to each <interfacename>AuthorityGranter</interfacename>
defined against the
<literal>AbstractJaasAuthenticationProvider.setAuthorityGranters(List)</literal>
property.</para>
<para>Spring Security does not include any production
<interfacename>AuthorityGranter</interfacename>s given that every JAAS principal has
an implementation-specific meaning. However, there is a
<literal>TestAuthorityGranter</literal> in the unit tests that demonstrates a simple
<literal>AuthorityGranter</literal> implementation.</para>
</section>
</section>
<section xml:id="jaas-defaultjaasauthenticationprovider">
<info>
<title>DefaultJaasAuthenticationProvider</title>
</info>
<para>The <classname>DefaultJaasAuthenticationProvider</classname> allows a JAAS
<classname>Configuration</classname> object to be injected into it as a dependency. It then
creates a <classname>LoginContext</classname> using the injected JAAS <classname>Configuration</classname>.
This means that <classname>DefaultJaasAuthenticationProvider</classname> is not bound any particular implementation
of <classname>Configuration</classname> as <classname>JaasAuthenticationProvider</classname> is.</para>
<section xml:id="jaas-inmemoryconfiguration">
<info>
<title>InMemoryConfiguration</title>
</info>
<para>In order to make it easy to inject a <classname>Configuration</classname> into
<classname>DefaultJaasAuthenticationProvider</classname>, a default in memory
implementation named <classname>InMemoryConfiguration</classname> is provided. The
implementation constructor accepts a <interfacename>Map</interfacename> where each key represents a
login configuration name and the value represents an <classname>Array</classname> of
<classname>AppConfigurationEntry</classname>s.
<classname>InMemoryConfiguration</classname> also supports a default
<classname>Array</classname> of <classname>AppConfigurationEntry</classname> objects that
will be used if no mapping is found within the provided <interfacename>Map</interfacename>. For
details, refer to the class level javadoc of <classname>InMemoryConfiguration</classname>.</para>
</section>
<section xml:id="jaas-djap-config">
<info>
<title>DefaultJaasAuthenticationProvider Example Configuration</title>
</info>
<para>While the Spring configuration for <classname>InMemoryConfiguration</classname> can be
more verbose than the standarad JAAS configuration files, using it in conjuction with
<classname>DefaultJaasAuthenticationProvider</classname> is more flexible than
<classname>JaasAuthenticationProvider</classname> since it not dependant on the default
<classname>Configuration</classname> implementation.</para>
<para>An example configuration of <classname>DefaultJaasAuthenticationProvider</classname> using
<classname>InMemoryConfiguration</classname> is provided below. Note that custom implementations of
<classname>Configuration</classname> can easily be injected into

<para>In a Spring Security deployment, Spring Security is responsible for this user
interaction (via the authentication mechanism). Thus, by the time the authentication
request is delegated through to JAAS, Spring Security's authentication mechanism
will already have fully-populated an <interfacename>Authentication</interfacename>
object containing all the information required by the JAAS
<literal>LoginModule</literal>.</para>
<para>Therefore, the JAAS package for Spring Security provides two default callback
handlers, <literal>JaasNameCallbackHandler</literal> and
<literal>JaasPasswordCallbackHandler</literal>. Each of these callback handlers
implement <literal>JaasAuthenticationCallbackHandler</literal>. In most cases these
callback handlers can simply be used without understanding the internal
mechanics.</para>
<para>For those needing full control over the callback behavior, internally
<literal>JaasAuthenticationProvider</literal> wraps these
<literal>JaasAuthenticationCallbackHandler</literal>s with an
<literal>InternalCallbackHandler</literal>. The
<literal>InternalCallbackHandler</literal> is the class that actually implements
JAAS’ normal <literal>CallbackHandler</literal> interface. Any time that the JAAS
<literal>LoginModule</literal> is used, it is passed a list of application context
configured <literal>InternalCallbackHandler</literal>s. If the
<literal>LoginModule</literal> requests a callback against the
<literal>InternalCallbackHandler</literal>s, the callback is in-turn passed to the
<literal>JaasAuthenticationCallbackHandler</literal>s being wrapped.</para>

<para>JAAS works with principals. Even "roles" are represented as principals in JAAS.
Spring Security, on the other hand, works with
<interfacename>Authentication</interfacename> objects. Each
<interfacename>Authentication</interfacename> object contains a single principal,
and multiple <interfacename>GrantedAuthority</interfacename>s. To facilitate
mapping between these different concepts, Spring Security's JAAS package includes an
<literal>AuthorityGranter</literal> interface.</para>
<para>An <literal>AuthorityGranter</literal> is responsible for inspecting a JAAS
principal and returning a set of <literal>String</literal>s, representing the
authorities assigned to the principal. For each returned authority string, the
<classname>JaasAuthenticationProvider</classname> creates a
<classname>JaasGrantedAuthority</classname> (which implements Spring Security’s
<interfacename>GrantedAuthority</interfacename> interface) containing the authority
string and the JAAS principal that the
<interfacename>AuthorityGranter</interfacename> was passed. The
<classname>JaasAuthenticationProvider</classname> obtains the JAAS principals by
firstly successfully authenticating the user’s credentials using the JAAS
<literal>LoginModule</literal>, and then accessing the
<literal>LoginContext</literal> it returns. A call to
<literal>LoginContext.getSubject().getPrincipals()</literal> is made, with each
resulting principal passed to each <interfacename>AuthorityGranter</interfacename>
defined against the
<literal>JaasAuthenticationProvider.setAuthorityGranters(List)</literal>
property.</para>
<para>Spring Security does not include any production
<interfacename>AuthorityGranter</interfacename>s given that every JAAS principal has
an implementation-specific meaning. However, there is a
<literal>TestAuthorityGranter</literal> in the unit tests that demonstrates a simple
<literal>AuthorityGranter</literal> implementation.</para>
