+<H1><A name="Authentication-Actors-Actors"></A>Actors</H1>
+
+<P>The authentication process involves a number of actors contributing to the concepts, the API and the particular implementations.</P>
+
+
+<H2><A name="Authentication-Actors-OSGiHttpServiceSpecification"></A>OSGi Http Service Specification</H2>
+
+<P>The main support for authentication is defined by the OSGi Http Service specification. This specification defines how an OSGi application can register servlets and resources to build web applications. As part of the servlet and/or resource registration a <TT>HttpContext</TT> may be provided, which allows for additional support.</P>
+
+<P>The main method of interest to the authentication process is the <TT>handleSecurity</TT> method. This is called by the OSGi Http Service implementation before the registered servlet is called. Its intent is to authenticate the request and to provide authentication information for the request object: the authentication type and the remote user name.</P>
+
+<P>The Sling Commons Auth bundle provides the <TT>AuthenticationSupport</TT> service which may be used to the implement the <TT>HttpContext.handleSecurity</TT> method.</P>
+
+
+<H2><A name="Authentication-Actors-SlingEngine"></A>Sling Engine</H2>
+
+<P>The Sling Engine implements the main entry point into the Sling system by means of the <TT>SlingMainServlet</TT>. This servlet is registered with the OSGi Http Service and provides a custom <TT>HttpContext</TT> whose <TT>handleSecurity</TT> method is implemented by the <TT>AuthenticationSupport</TT> service.</P>
+
+<P>When the request hits the <TT>service</TT> method of the Sling Main Servlet, the resource resolver provided by the <TT>AuthenticationSupport</TT> service is retrieved from the request attributes and used as the resource resolver for the request.</P>
+
+<P>That's all there is for the Sling Engine to do with respect to authentication.</P>
+
+
+<H2><A name="Authentication-Actors-SlingCommonsAuth"></A>Sling Commons Auth</H2>
+
+<P>The support for authenticating client requests is implemented in the Sling Commons Auth bundle. As such this bundle provides three areas of support</P>
+
+<UL>
+	<LI><TT>AuthenticationHandler</TT> service interface. This is implemented by services providing functionality to extract credentials from HTTP requests.</LI>
+	<LI><TT>Authenticator</TT> service interface. This is implemented by the <TT>SlingAuthenticator</TT> class in the Commons Auth bundle and provides applications with entry points to login and logout.</LI>
+	<LI><TT>AuthenticationSupport</TT> service interface. This is implemented by the <TT>SlingAuthenticator</TT> class in the Commons Auth bundle and allows applications registering with the OSGi HTTP Service to make use of the Sling authentication infrastructure.</LI>
+</UL>
+
+
+
+<H2><A name="Authentication-Actors-JCRRepository"></A>JCR Repository</H2>
+
+<P>The actual process of logging into the repository and provided a <TT>Session</TT> is implementation dependent. In the case of Jackrabbit extensibility is provided by configuration of the Jackrabbit repository by means of an interface and two helper classes:</P>
+
+<UL>
+	<LI><TT>LoginModule</TT> &ndash; The interface to be implemented to provide login processing plugins</LI>
+	<LI><TT>AbstractLoginModule</TT> &ndash; A an abstract base class implementation of the <TT>LoginModule</TT> interface.</LI>
+	<LI><TT>DefaultLoginModule</TT> &ndash; The default implementation of the <TT>AbstractLoginModule</TT> provided by Jackabbit. This login module takes <TT>SimpleCredentials</TT> and uses the repository to lookup the users, validate the credentials and providing the <TT>Principal</TT> representing the user towards the repository.</LI>
+</UL>
+
+
+<P>The Sling Jackrabbit Embedded Repository bundle provides additional plugin interfaces to extend the login process dynamically using OSGi services. To this avail the bundle configures a <TT>LoginModule</TT> with the provided default Jackrabbit configuration supporting these plugins:</P>
+
+<UL>
+	<LI><TT>LoginModulePlugin</TT> &ndash; The main service interface. Plugins must implement this interface to be able to extend the login process. See for example the <A href="http://svn.apache.org/repos/asf/sling/trunk/bundles/extensions/openidauth/" class="external-link" rel="nofollow">Sling OpenID authentication handler</A>, which implements this interface to support OpenID authentication.</LI>
+	<LI><TT>AuthenticationPlugin</TT> &ndash; Helper interface for the <TT>LoginModulePlugin</TT>.</LI>
+</UL>
+
+
+
+<H2><A name="Authentication-Actors-SlingApplications"></A>Sling Applications</H2>
+
+<P>Sling Applications requiring authenticed requests should not care about how authentication is implemented. To support such functionality the <TT>Authenticator</TT> service is provided with two methods:</P>
+
+<UL>
+	<LI><TT>login</TT> &ndash; allows the application to ensure requests are authenticated. This involves selecting an <TT>AuthenticationHandler</TT> to request credentials for authentication.</LI>
+</UL>
+
+
+<UL>
+	<LI><TT>logout</TT> &ndash; allows the application to forget about any authentication. This involves selecting an <TT>AuthenticationHandler</TT> to forget about credentials in the request.</LI>
+</UL>
+
+
+<P>Sling Applications should never directly use any knowledge of any authentication handler or directly call into an authentication handler. This will certainly break the application and cause unexpected behaviour.</P>

+<P>Interestingly the <TT>dropCredentials</TT> method is implemented in the same way as the <TT>requestCredentials</TT> method. The reason for this is, that HTTP Basic authentication does not have a notion of login and logout. Rather the request is accompanied with an <TT>Authorization</TT> header or not. The contents of this header is usually cached by the client browser. So logout is actually simulated by sending a 401/UNAUTHORIZED status thus causing the client browser to clear the cache and ask for user name and password.</P>

+
+<P>The core piece of functionality with respect to authentication in Sling is contained in the Sling Commons Auth bundle. This bundle provides the API for Sling and Sling applications to make use of authentication.</P>
+
+<P>This support encompasses three parts:</P>
+
+<UL>
+	<LI>The <TT>AuthenticationSupport</TT> service provided by the <TT>SlingAuthenticator</TT> class. This service can be used by implementations of the OSGi <TT>HttpContext</TT> interface to delegate authentication.</LI>
+	<LI>The <TT>Authenticator</TT> service also provided by the <TT>SlingAuthenticator</TT> class. This service may be used by Sling Applications to help clients login and logout.</LI>
+	<LI>The <TT>AuthenticationHandler</TT> service interface. These services may be implemented by extensions to support various ways for transporting credentials from clients to the Sling server.</LI>
+</UL>
+
+
+<P>This page describes how the <TT>SlingAuthenticator</TT> class provides the <TT>AuthenticationSupport</TT> and  <TT>Authenticator</TT> services. For a description of the <TT>AuthenticationHandler</TT> service interface and the interaction between the <TT>SlingAuthenticator</TT> and the <TT>AuthenticationHandler</TT> services refer to the <A href="authentication-authenticationhandler.html" title="Authentication - AuthenticationHandler">AuthenticationHandler</A> page.</P>
+
+<P>The <TT>SlingAuthenticator</TT> class is an internal class of the <TT>org.apache.sling.commons.auth</TT> bundle and implements the <TT>Authenticator</TT> and <TT>AuthenticationSupport</TT> services.</P>
+
+
+<H2><A name="Authentication-Framework-AuthenticationSupport"></A>AuthenticationSupport</H2>
+
+<P>The <TT>AuthenticationSupport</TT> service interface defines a single method: <TT>handleSecurity</TT>. This method is intended to be called by the <TT>handleSecurity</TT> method of any <TT>HttpContext</TT> implementation wishing to make use of the Sling Authentication Framework.</P>
+
+<P>The Sling Authenticator implementation selects an <TT>AuthenticationHandler</TT> service appropriate for the request and calls the <TT>AuthenticationHandler.extractCredentials</TT> method to extract the credentials from the request. If no credentials could be extracted, the Sling Authenticator either admits the request as an anonymous request or requests authentication from the client by calling its own <TT>login</TT> method.</P>
+
+
+<P>The implementation follows this algorithm:</P>
+
+<OL>
+	<LI>Select one or more <TT>AuthenticationHandler</TT> for the request according to the request URL's scheme and authorization part.</LI>
+	<LI>Call the <TT>extractCredentials</TT> method of each authentication handler, where the order of handler call is defined by the length of the registered path: handlers registered with longer paths are called before handlers with shorter paths. The goal is to call the handlers in order from longest request path match to shortest match. Handlers not matching the request path at all are not called.</LI>
+	<LI>The first handler returning a non-<TT>null</TT> <TT>AuthenticationInfo</TT> result &quot;wins&quot; and the result is used for authentication.</LI>
+	<LI>If any <TT>AuthenticationInfoPostProcessor</TT> services are registered, the <TT>AuthenticationInfo</TT> object is passed to their <TT>postProcess()</TT> method.</LI>
+	<LI>If no handler returns a non-<TT>null</TT> result, the request may be handled anonymously. In these cases, an empty <TT>AuthenticationInfo</TT> object is passed to any <TT>AuthenticationInfoPostProcessor</TT> services.</LI>
+	<LI>(Try to) log into the repository either with the provided credentials or anonymously.</LI>
+	<LI>If there were credentials provided and the login was successful, a login event is posted <B>if</B> the <TT>AuthenticationInfo</TT> object contains a non-null object with the key <TT>$$auth.info.login$$</TT> (<TT>AuthConstants.AUTH_INFO_LOGIN</TT>). This event is posted with the topic <TT>org/apache/sling/auth/core/Authenticator/LOGIN</TT>. (added in Sling Auth Core 1.1.0)</LI>
+	<LI>Set request attributes listed below.</LI>
+</OL>

+<UL>
+	<LI>Global setting of whether anonymous requests are allowed or not. This is the value of the <EM>Allow Anonymous Access</EM> (<TT>auth.annonymous</TT>) property of the <TT>SlingAuthenticator</TT> configuration. This property is supported for backwards compatibility and defaults to <TT>true</TT> (allowing anonymous access).</LI>
+	<LI>Specific configuration per URL. The <EM>Authentication Requirements</EM> (<TT>sling.auth.requirements</TT>) property of the <TT>SlingAuthenticator</TT> configuration may provide a list of URLs for which authentication may be required or not: Any entry prefixed with a dash <TT>-</TT> defines a subtree for which authentication is not required. Any entry not prefixed with a dash or prefixed with a plus <TT>+</TT> defines a subtree for which authentication is required up front and thus anonymous access is not allowed. This list is empty by default.</LI>
+	<LI>Any OSGi service may provide a <TT>sling.auth.requirements</TT> registration property which is used to dynamically extend the authentication requirements from the <EM>Authentication Requirements</EM> configuration. This may for example be set by <TT>AuthenticationHandler</TT> implementations providing a login form to ensure access to the login form does not require authentication. The value of this property is a single string, an array of strings or a Collection of strings and is formatted in the same way as the <EM>Authentication Requirements</EM> configuration property.</LI>
+</UL>
+
+
+<P>The URLs set on the <EM>Authentication Requirements</EM> configuration property or the <TT>sling.auth.requirements</TT> service registration property can be absolute paths or URLs like the <TT>path</TT> service registration property of <TT>AuthenticationHandler</TT> services. This allows the limitation of this setup to certain requests by scheme and/or virtual host address.</P>

+
+
+
+<P>This section describes the framework provided by Sling to authenticate HTTP requests.</P>
+
+<P>Let's look at generic request processing of Sling: Sling is linked into the outside world by registering the Sling Main Servlet &ndash; implemented by the <TT>SlingMainServlet</TT> class in the Sling Engine bundle &ndash; with an OSGi <TT>HttpService</TT>. This registration is accompanyied with an implementation instance of the OSGi <TT>HttpContext</TT> interface, which defines a method to authenticate requests: <TT>handleSecurity</TT>.</P>
+
+<P>This method is called by the OSGi HTTP Service implementation after the servlet has been selected to handle the request but before actually calling the servlet's <TT>service</TT> method.</P>
+
+<TABLE class="sectionMacro" border="0" cellpadding="5" cellspacing="0" width="100%"><TBODY><TR>
+<TD class="confluenceTd" valign="top">
+<P><SPAN class="image-wrap" style=""><A class="confluence-thumbnail-link 602x622" href="authentication.data/authentication.png"><IMG src="authentication.data/authentication.png.jpeg" title="Request Processing " style="border: 0px solid black"></A></SPAN></P></TD>
+<TD class="confluenceTd" valign="top">
+<OL>
+	<LI>First the OSGi HTTP Service implementation is analyzing the request URL to find a match for a servlet or resource registered with the HTTP Service.</LI>
+	<LI>Now the HTTP Service implementation has to call the <TT>handleSecurity</TT> method of the <TT>HttpContext</TT> object with which the servlet or resource has been registered. This method returns <TT>true</TT> if the request should be serviced. If this method returns <TT>false</TT> the HTTP Service implementation terminates the request sending back any response which has been prepared by the <TT>handleSecurity</TT> method. Note, that the <TT>handleSecurity</TT> method must prepare the failure response sent to the client, the HTTP Service adds nothing here. If the <TT>handleSecurity</TT> method is successful, it must add two (or three) request attributes described below.</LI>
+	<LI>When the <TT>handleSecurity</TT> method returns <TT>true</TT> the HTTP Service either calls the <TT>Servlet.service</TT> method or sends back the requested resource depending on whether a servlet or a resource has been selected in the first step.</LI>
+</OL>
+</TD></TR></TBODY></TABLE>
+
+<P>The important thing to note here is, that at the time the <TT>handleSecurity</TT> method is called, the <TT>SlingMainServlet</TT> is not yet in control of the request. So any functionality added by the <TT>SlingMainServlet</TT>, notably the <TT>SlingHttpServletRequest</TT> and <TT>SlingHttpServletResponse</TT> objects are not available to the implementation of the <TT>handleSecurity</TT> method.</P>
+
+<P>The following pages describe the full details of request authentication in Sling in full detail:</P>

+	<LI><A href="authentication-tasks.html" title="Authentication - Tasks">Tasks</A>: Authentication of HTTP Requests is generally a two-step process: First the credentials must be extracted from the request and second the credentials must be validated.

+
+<P>Providing bundles have a Bundle manifest header <TT>Sling-Bundle-Resources</TT> containing a list of absolute paths provided by the bundle. The paths are separated by comma or whitespace (SP, TAB, VTAB, CR, LF). </P>

+    /libs/sling/servlet/<SPAN class="code-keyword">default</SPAN>/explorer
+...
+</PRE>
+</DIV></DIV>
+
+<P>It's also possible to map resources from the bundle to a different location in the resource tree. In this case the path has to be extended with a path attrribute to declare where the resources are in the bundle:</P>
