+ 	    <faq>
+ 	    	<question>My application goes into an "endless loop" when I try to login, what's going on?</question>
+ 	    	<answer><p>A common user problem with infinite loop and redirecting to the login page is caused 
+ 	    		by accidently configuring the login page as a "secured" resource. Make sure your configuration
+ 	    		allows anonymous access to the login page, either by excluding it from the security filter
+ 	    		chain or marking it as requiring ROLE_ANONYMOUS.</p>
+ 	    		<p>If your AccessDecisionManager includes an AutheticatedVoter, you can use the attribute
+ 	    			"IS_AUTHENTICATED_ANONYMOUSLY". This is automatically available if you are using the
+ 	    			standard namespace configuration setup.
+ 	    		</p>
+ 	    		<p>
+ 	    			From Spring Security 2.0.1 onwards, when you are using namespace-based configuration, a check will be made 
+ 	    			on loading the application context and a warning message logged if your login page appears to be protected.
+ 	    		</p>

+    		<question>I get an exception with the message "Access is denied (user is anonymous);". What's wrong?</question>
+    		<answer>
+    			<p>
+    			This is a debug level message which occurs the first time an anonymous user attempts to access a protected
+    			resource.
+    			<pre>
+DEBUG [ExceptionTranslationFilter] - Access is denied (user is anonymous); redirecting to authentication entry point
+org.springframework.security.AccessDeniedException: Access is denied

+    at org.springframework.security.intercept.AbstractSecurityInterceptor.beforeInvocation(AbstractSecurityInterceptor.java:262)    				
+    			</pre>
+    				It is normal and shouldn't be anything to worry about.
