Like this fellow here, I'm trying to port a Tomcat application to WebLogic.
I have a few resources protected by security rules in web.xml. Instead of BASIC, I'm using FORM authentication, but that should be irrelevant.
In Tomcat, it's very easy to set up a simple security realm, by editing conf/tomcat-users.xml.
How do I set up a simple security realm in Weblogic ? All I want is to have the user to input his username and password and have it authenticated by the container.
<security-constraint>
<web-resource-collection>
<web-resource-name>basic-auth security</web-resource-name>
<url-pattern>/*</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>HELLO_USER</role-name>
</auth-constraint>
<user-data-constraint>NONE</user-data-constraint>
</security-constraint>
<login-config>
<auth-method>FORM</auth-method>
<realm-name>somerealm</realm-name>
<form-login-config>
<form-login-page>login.jsp</form-login-page>
<form-error-page>error.jsp</form-error-page>
</form-login-config>
</login-config>
<security-role>
<role-name>HELLO_USER</role-name>
</security-role>
there is a default weblogic realm called "myrealm". Create the user(s) there using the weblogic web console. Also create a group (i.e. HELLO_GROUP) and assign your user(s) to that group.
Create a weblogic.xml file and map the HELLO_USER role onto the HELLO_GROUP with a structure like:
<weblogic-web-app>
...
<security-role-assignment>
<role-name>HELLO_USER</role-name>
<principal-name>HELLO_GROUP</principal-name>
</security-role-assignment>
...
</weblogic-web-app>

Running Tomcat 7, I am trying to configure the /conf/web.xml on the Tomcat server to secure some URLs with basic authentication and to provide some other URLs for public access.
The tomcat-users.xml contains following role and user:
<role rolename="test-ui"/>
<user username="paul" password="password" roles="test-ui"/>
I have added the following section to Tomcats /conf/web.xml
<security-constraint>
<web-resource-collection>
<web-resource-name>Public access</web-resource-name>
<url-pattern>/docs/*</url-pattern>
</web-resource-collection>
</security-constraint>
<security-constraint>
<web-resource-collection>
<web-resource-name>Protected access</web-resource-name>
<url-pattern>/*</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>test-ui</role-name>
</auth-constraint>
</security-constraint>
<security-role>
<description>Protected access</description>
<role-name>test-ui</role-name>
</security-role>
<login-config>
<auth-method>BASIC</auth-method>
</login-config>
So there are two 'security-constraint' elements, the public one does not contain the 'auth-constraint', which actually should mean, there is no authentication necessary.
When I open the URL
http://localhost:8080
Tomcat asks for authentication.
This is fine, however when I open the URL
http://localhost:8080/docs/
Tomcat also asks for authentication and for my understanding this is configured as a "non secure" URL - so public acccess, but it does not behave like this.
What did I wrong in the configuration or is this scenario not supposed to work like this?
Thanks.

You need the <auth-constraint> node in the <security-constraint>, even it is empty e.g. <auth-constraint/>
If an security-constraint does not exists, the Container MUST allow unauthenticated access for these URL. security-constraint is optional.
I have following web.xml file I kept welcome page into security check so that it would redirect to login page but the welcome page is displayed without user loggin in. Is this the correct way?
<welcome-file-list>
<welcome-file>/GISPages/welcome.xhtml</welcome-file>
</welcome-file-list>
<resource-ref>
<res-ref-name>jdbc/Gis_WebApp</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
<security-constraint>
<web-resource-collection>
<web-resource-name>Protected Pages</web-resource-name>
<url-pattern>/GISPages/*</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>registereduser</role-name>
<role-name>admin</role-name>
</auth-constraint>
</security-constraint>
<login-config>
<auth-method>FORM</auth-method>
<realm-name>Live</realm-name>
<form-login-config>
<form-login-page>/login.xhtml</form-login-page>
<form-error-page>/noauth.xhtml</form-error-page>
</form-login-config>
</login-config>
<security-role>
<role-name>registereduser</role-name>
</security-role>
<security-role>
<role-name>admin</role-name>
</security-role>
Security constraints protects a URL pattern, but in this case due to welcome-file setting your default URL will change to something like http://:port/webcontext/ and welcome.xhtml will be displayed. Whereas as per the URL pattern defined a protected URL should have URL like http://:port/webcontext/GISPages/welcome.xhtml
Since the URL pattern did not match the application server render the page content.
Only solution which worked for me is to check UserPrincipal in prerender event
<f:event type="preRenderComponent"
listener="#{bean.forwardToLoginIfNotLoggedIn}" />
and redirect to login.xhtml if UserPrincipal returns null.
Apologies for opening an old thread. I recently faced similar issue hence thought that this might be useful to some.
I have a Java EE app server (jboss-eap-4.3) and several .wars that make up a larger web application. The idea is that a .war can be run separately or linked from another .war. As they are all part of the same app concepually, we don't want to present several logins.
I want to configure the .wars so that they all share the same security-constraints and security roles. Basically this part of web.xml:
<security-constraint>
<web-resource-collection>
<url-pattern>/*</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>Admin</role-name>
</auth-constraint>
<security-constraint>
<security-role>
<role-name>Admin</role-name>
</security-role>
<login-config>
<auth-method>BASIC</auth-method>
<realm-name>WebApp</realm-name>
</login-config>
Our roles have been changing often lately and we're adding new .wars periodically as well. Additionally we change the auth-method depending on the deployment environment, which adds another reason to tweak. Ideally I'd like a way to break off the security portion of the web.xml so it can be "inherited" by the others. I thought realms might be a good place to look for this, but I didn't turn up anything promising.
Note that there are still other web apps in this container with a completely different security-domain, so a global setting for tomcat may not be appropriate.
Not a great answer, but I ended up automating the dirty work with ant macrodefs like the one below.
<!--
| Take a "plain" web.xml and add security settings to it.
| This will add BASIC authentication with Admin, Operator, and Guest role access
|
-->
<taskdef resource="net/sf/antcontrib/antlib.xml" />
<macrodef name="addSecurityToWeb.xml">
<attribute name="file"/>
<sequential>
<if>
<not>
<isfileselected file="#{file}">
<contains text="login-config" ignorewhitespace="true"/>
</isfileselected>
</not>
<then>
<replace file="#{file}">
<replacetoken><![CDATA[</web-app>]]></replacetoken>
<replacevalue>

I've implemented a own LoginCommand and it works perfectly for all the remote calls from flex. But beside the flex remote objects I'd like to protect some other web resources like html, jsp and swf files so I added a security-constraint with url pattern in the web.xml.
<security-constraint>
<web-resource-collection>
<web-resource-name>FlexClient Secure Webapp</web-resource-name>
<description>Security constraint /secure</description>
<url-pattern>/main.jsp</url-pattern>
<http-method>POST</http-method>
<http-method>GET</http-method>
</web-resource-collection>
<auth-constraint>
<description>only authenticated user</description>
<role-name>flexclient-user</role-name>
</auth-constraint>
</security-constraint>
<login-config>
<auth-method>FORM</auth-method>
<form-login-config>
<form-login-page>/login.jsp</form-login-page>
<form-error-page>/login.jsp</form-error-page>
</form-login-config>
</login-config>
<security-role>
<role-name>flexclient-user</role-name>
</security-role>
Security configuration in services-config.xml
<security>
<login-command class="ch.tie.iengine.flex.security.LoginCommand" server="all" >
<per-client-authentication>false</per-client-authentication>
</login-command>
<security-constraint id="trusted">
<auth-method>Custom</auth-method>
<roles>
<role>flexclient-user</role>
</roles>
</security-constraint>
</security>
But even I got once authenticated successfully through remote calls I can not call the other resources. It always forwards me to login.jsp.
Does anyone had a similar issue?
I have already created a user database file using Apache's htpasswd command. This file is now used by several other application like apache and subversion.
Users in are created like this:
htpasswd /path/to/users.htpasswd peter
This user file is global, not per directory.
How I can make Tomcat 6 use this same file as a security realm?
Most similar to the htpasswd may be the MemoryRealm.
I had problems myself to find a simple example how to use it, so I'll post an easy example code here:
Set up a role, username and password in tomcat-users.xml
Your web.xml should contain something like:
<security-constraint>
<web-resource-collection>
<web-resource-name>
My Protected WebSite
</web-resource-name>
<url-pattern> /* </url-pattern>
<http-method> GET </http-method>
<http-method> POST </http-method>
</web-resource-collection>
<auth-constraint>
<!-- the same like in your tomcat-users.conf file -->
<role-name> test </role-name>
</auth-constraint>
</security-constraint>
<login-config>
<auth-method> BASIC </auth-method>
<realm-name> Basic Authentication </realm-name>
</login-config>
<security-role>
<description> Test role </description>
<role-name> test </role-name>
</security-role>
Add this to your server.xml file:
<Realm className="org.apache.catalina.realm.MemoryRealm"></Realm>
To secure access to your Tomcat webapp, you can implement your simple security constraint (e.g. in /var/lib/tomcat7/webapps/*/WEB-INF/web.xml) as below (just add it before </web-app> ending):
<!-- This security constraint protects your webapp interface. -->
<login-config>
<!-- Define the Login Configuration -->
<auth-method>BASIC</auth-method>
<realm-name>Webapp</realm-name>
</login-config>
<security-constraint>
<web-resource-collection>
<web-resource-name>Admin</web-resource-name>
<url-pattern>/*</url-pattern>
<http-method>GET</http-method>
<http-method>POST</http-method>
</web-resource-collection>
<auth-constraint>
<role-name>*</role-name>
</auth-constraint>
<!-- Specifying a Secure Connection -->
<user-data-constraint>
<!-- transport-guarantee can be CONFIDENTIAL (forced SSL), INTEGRAL, or NONE -->
<transport-guarantee>NONE</transport-guarantee>
</user-data-constraint>
</security-constraint>
<!-- Authorization, see: tomcat-users.xml -->
<security-role>
<role-name>*</role-name>
</security-role>
The login-config element contains the auth-method element, which specifies the authentication method that we use, which is BASIC. The security-constraint element contains 3 elements: web-resource-collection, auth-constraint, and user-data-constraint. The web-resource-collection specifies the parts of our application that require authentication. The /* indicates that the whole application requires authentication. The auth-constraint specifies the role that a user needs to have in order to access the protected resources. The user-data-constraint's transport-guarantee can be NONE, CONFIDENTIAL or INTEGRAL. We set it to NONE, which means that redirecting to SSL is not required when you try to hit the protected resource.
Also make sure that you've line:
<Realm className="org.apache.catalina.realm.MemoryRealm" />
inside your conf/server.xml (Engine section).
If you have not changed any configuration files, please examine the file conf/tomcat-users.xml in your installation (locate tomcat-users.xml). That file must contain the credentials to let you use Tomcat webapp.
For example, to add the manager-gui role to a user named tomcat with a password of s3cret, add the following to the config file listed above:
<role rolename="manager-gui"/>
<user username="tomcat" password="s3cret" roles="manager-gui"/>
Then you can access your webapps manager from /manager/html (e.g. reloading after config changes).
Read more: Manager App HOW-TO.
Then restart your Tomcat and when accessing your webapp, it should ask you for the right credentials.

How do I use Basic authentication with Tomcat?
There are two options:
Use Apache as a front end to the tomcat (using either mod_jk or mod_proxy_ajp) and the Apache do the authentication. You can find details on how to do so here
If you want the tomcat to do the authentication, then you need ot use something else than the htpasswd file. There are 4 ways to save the users' credentials - using database, JNDI/LDAP, an XML file or a JAAS provider. You can read about all the options in the Realm Configuration HOW-TO.
