Help getting form-based authentication example working

Hello,

I'm having problems getting the form-based authentication example that 
ships with Tomcat 6 to work properly.

I have followed all the instructions at

http://tomcat.apache.org/tomcat-6.0-doc/realm-howto.html

to make the form authentication example using MemoryRealm to work for

http://myserver:9090/examples/jsp/security/protected/

but when I access this URL, I get the protected page that says:

You are logged in as remote user null in session BLAH...
No user principal could be identified.

I understand that this page should redirect me to the login.jsp page 
instead where I can enter user1/test.


Here's what I did:

$CATALINA_HOME/conf/server.xml:

<Realm className="org.apache.catalina.realm.MemoryRealm" />


$CATALINA_HOME/conf/tomcat-users.xml:

<tomcat-users>
   <role rolename="tomcat"/>
   <role rolename="role1"/>
   <user username="user2" password="test" roles="role1"/>
   <user username="user1" password="test" roles="tomcat"/>
</tomcat-users>


$CATALINA_HOME/webapps/examples/WEB-INF/web.xml:

<security-constraint>
       <display-name>Example Security Constraint</display-name>
       <web-resource-collection>
          <web-resource-name>Protected Area</web-resource-name>
	 <!-- Define the context-relative URL(s) to be protected -->
          <url-pattern>/security/protected/*</url-pattern>
	 <!-- If you list http methods, only those methods are protected -->
	 <http-method>DELETE</http-method>
          <http-method>GET</http-method>
          <http-method>POST</http-method>
	 <http-method>PUT</http-method>
       </web-resource-collection>
       <auth-constraint>
          <!-- Anyone with one of the listed roles may access this area -->
          <role-name>tomcat</role-name>
	 <role-name>role1</role-name>
       </auth-constraint>
     </security-constraint>

     <!-- Default login configuration uses form-based authentication -->
     <login-config>
       <auth-method>FORM</auth-method>
       <realm-name>Example Form-Based Authentication Area</realm-name>
       <form-login-config>
 
<form-login-page>/jsp/security/protected/login.jsp</form-login-page> 
   <form-error-page>/jsp/security/protected/error.jsp</form-error-page>
       </form-login-config>
     </login-config>


Any help would be much appreciated.  I'm running Tomcat on a Solaris 
workstation and accessing it from my Windows client with Firefox.

Regards,
Frank

Do you mean you are leaving users out on purpose for security reasons? 
So I guess you'll change the documentation to tell the reader to add the 
users themselves.

Thanks for updating the document, Rémy.

No default users will be provided.

It has a functionally equivalent realm.

The rest has been fixed, thanks.

Form-based authentication example broken in Tomcat 6.0

Posted by Frank McCown <fm...@cs.odu.edu>.
I noticed the MemoryRealm / form-based authentication example in Tomcat 
6.0 is broken.  The example works just fine in Tomcat 5.5, but in the 
migration to 6.0, it got broken.  According to the doc at

http://tomcat.apache.org/tomcat-6.0-doc/realm-howto.html

the app is supposed to be available at

http://localhost:8080/jsp-examples/security/protected/

but the URL is actually

http://localhost:8080/examples/jsp/security/protected/


The default contents of the conf/tomcat-users.xml file *should* be

<tomcat-users>
   <user name="tomcat" password="tomcat" roles="tomcat" />
   <user name="role1"  password="tomcat" roles="role1"  />
   <user name="both"   password="tomcat" roles="tomcat,role1" />
</tomcat-users>

but the file that ships with 6.0 is missing all the <user> tags.


And the server.xml file is missing the line:

<Realm className="org.apache.catalina.realm.MemoryRealm" />


Finally the web.xml file is using the wrong <url-pattern>.  It is set to

<url-pattern>/security/protected/*</url-pattern>

but should be

<url-pattern>/jsp/security/protected/*</url-pattern>

Making these changes will fix the example.  Hope someone working on 
Tomcat sees this post.

Regards,
Frank
