<h1><a name="Security-Authentication"></a>Authentication</h1>

<p>Container or Spring Security managed authentication as well as the custom authentication
are all the viable options used by CXF developers.</p>

<p>Starting from CXF 2.3.2 and 2.4.0 it is possible to use an org.apache.cxf.interceptor.security.JAASLoginInterceptor
in order to authenticate a current user and populate a CXF SecurityContext.</p>

<p>Example :</p>

<div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent">
<pre class="code-xml">
<span class="code-tag">&lt;jaxws:endpoint address=<span class="code-quote">"/soapService"</span>&gt;</span>
 <span class="code-tag">&lt;jaxws:inInterceptors&gt;</span>
   <span class="code-tag">&lt;ref bean=<span class="code-quote">"authenticationInterceptor"</span>/&gt;</span>
 <span class="code-tag">&lt;/jaxws:inInterceptors&gt;</span>
<span class="code-tag">&lt;/jaxws:endpoint&gt;</span>

<span class="code-tag">&lt;bean id=<span class="code-quote">"authenticationInterceptor"</span>
class=<span class="code-quote">"org.apache.cxf.interceptor.security.JAASLoginInterceptor"</span>&gt;</span>
   <span class="code-tag">&lt;property name=<span class="code-quote">"contextName"</span>
value=<span class="code-quote">"jaasContext"</span>/&gt;</span>
   &lt;!--
     Deprecated starting from 2.4.4 and 2.5.0 
     <span class="code-tag">&lt;property name=<span class="code-quote">"rolePrefix"</span>
value=<span class="code-quote">"ROLE_"</span>/&gt;</span>
   --&gt;
   <span class="code-tag">&lt;property name=<span class="code-quote">"roleClassifier"</span>
value=<span class="code-quote">"ROLE_"</span>/&gt;</span>

<span class="code-tag">&lt;/bean&gt;</span>
<span class="code-tag"><span class="code-comment">&lt;!-- Similarly for JAX-RS
endpoints --&gt;</span></span>
</pre>
</div></div> 

<p>The JAAS authenticator is configured with the name of the JAAS login context (the
one usually specified in the JAAS configuration resource which the server is aware of). It
is also configured with an optional "roleClassifier" property which is needed by the CXF SecurityContext
in order to differentiate between user and role Principals. By default CXF will assume that
role Principals are represented by javax.security.acl.Group instances.</p>

<p>In some cases objects representing a user principal and roles are implementing the
same marker interface such as Principal. That can be handled like this:</p>

<div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent">
<pre class="code-xml">

<span class="code-tag">&lt;bean id=<span class="code-quote">"authenticationInterceptor"</span>
class=<span class="code-quote">"org.apache.cxf.interceptor.security.JAASLoginInterceptor"</span>&gt;</span>
   <span class="code-tag">&lt;property name=<span class="code-quote">"contextName"</span>
value=<span class="code-quote">"jaasContext"</span>/&gt;</span>
   <span class="code-tag">&lt;property name=<span class="code-quote">"roleClassifier"</span>
value=<span class="code-quote">"RolePrincipal"</span>/&gt;</span>
   <span class="code-tag">&lt;property name=<span class="code-quote">"roleClassifierType"</span>
value=<span class="code-quote">"classname"</span>/&gt;</span>
<span class="code-tag">&lt;/bean&gt;</span>
<span class="code-tag"><span class="code-comment">&lt;!-- Similarly for JAX-RS
endpoints --&gt;</span></span>
</pre>
</div></div> 

<p>In this case JAASLoginInterceptor will know that the roles are represented by a class
whose simple name is RolePrincipal. Note that full class names are also supported.</p>


<h1><a name="Security-WSSecurityUsernameTokenandCustomAuthentication"></a>WS-Security
UsernameToken and Custom Authentication</h1>

<p>If needed, one may want to configure a jaxws:endpoint with a "ws-security.ut.no-callbacks"
property set to true and register a custom org.apache.cxf.interceptor.security.AbstractUsernameTokenInterceptor
implementation for using a WSS4J UsernameToken wrapped in a CXF specific UsernameToken for
the custom authentication and Subject creation. JAASLoginInterceptor will also recognize a
CXF UsernameToken and thus can be used instead of the custom org.apache.cxf.interceptor.security.AbstractUsernameTokenInterceptor.</p>

<p>Note that the "ws-security.ut.no-callbacks" property has been renamed to "ws-security.validate.token"
in CXF 2.4.0. The name of the property is 'positive' thus one will need to set this property
to false in order to postpone the validation of the token.</p>

<h1><a name="Security-Authorization"></a>Authorization</h1>

<p>Container or Spring Security managed authorization as well as the custom authorization
are all the viable options used by CXF developers.</p>

<p>CXF 2.3.2 and 2.4.0 introduce org.apache.cxf.interceptor.security.SimpleAuthorizingInterceptor
and org.apache.cxf.interceptor.security.SecureAnnotationsInterceptor interceptors which can
help with enforcing the authorization rules.</p>

<p>Example :</p>

<div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent">
<pre class="code-xml">
<span class="code-tag">&lt;jaxws:endpoint id=<span class="code-quote">"endpoint1"</span>

   <span class="code-tag">&lt;ref bean=<span class="code-quote">"authorizationInterceptor"</span>/&gt;</span>
 <span class="code-tag">&lt;/jaxws:inInterceptors&gt;</span>
<span class="code-tag">&lt;/jaxws:endpoint&gt;</span>

<span class="code-tag">&lt;bean id=<span class="code-quote">"authorizationInterceptor"</span>
