Security Role Mapping in Spring Security.

I am new to springs security and trying to configure spring security in my application. My application server is WAS. Initially the application security was set up as below in deployment descriptor.



Now I have configured the application using spring security as below.



When I deploy my application in WAS earlier, USER role would map to security role mappings. All users configured in AD base will be thus validated.

Now -

How can I set up the USER Role in Spring Security?

Can I mention the security role as done in web.xml explicitly so that there are no username/password listed in security file as above.

You can use
<sec:authentication-manager alias="authenticationManager">
<sec:authentication-provider ref="preauthAuthProvider" />
</sec:authentication-manager>

<bean id="preauthAuthProvider" class="org.springframework.security.web.authentication.preauth.PreAuthenticatedAuthenticationProvider">
<property name="preAuthenticatedUserDetailsService">
<bean id="userDetailsServiceWrapper" class="org.springframework.security.core.userdetails.UserDetailsByNameServiceWrapper">
<property name="userDetailsService" ref="userDetailsService" />
</bean>
</property>
</bean>

Where userDetailService is the service which will return all the user related inforamtion and you can map roles using below code

<bean id="userDetailsService" class="Your Service Class">
<property name="userRoles2GrantedAuthoritiesMapper">
<bean class="org.springframework.security.core.authority.mapping.SimpleAttributes2GrantedAuthoritiesMapper">
<property name="attributePrefix" value="ROLE_" />
</bean>
</property>
</bean>
 
It is sorta covered in the JavaRanch Style Guide.
