8.4. Configuring Authentication and Role Mapping using JBoss EAP Login Modules

download PDF
When using Red Hat JBoss EAP log in module for querying roles from LDAP, you must implement your own mapping of Principals to Roles, as JBoss EAP uses its own custom classes. The following example demonstrates how to map a principal obtained from JBoss EAP login module to a role. It maps user principal name to a role, performing a similar action to the IdentityRoleMapper:

Example 8.1. Mapping a Principal from JBoss EAP's Login Module

public class SimplePrincipalGroupRoleMapper implements PrincipalRoleMapper {
   @Override
   public Set<String> principalToRoles(Principal principal) {
      if (principal instanceof SimpleGroup) {
         Enumeration<Principal> members = ((SimpleGroup) principal).members();
         if (members.hasMoreElements()) {
            Set<String> roles = new HashSet<String>();
            while (members.hasMoreElements()) {
               Principal innerPrincipal = members.nextElement();
               if (innerPrincipal instanceof SimplePrincipal) {
                  SimplePrincipal sp = (SimplePrincipal) innerPrincipal;
                  roles.add(sp.getName());
               }
            }
            return roles;
         } 
      }
      return null;
   }
}

Example 8.2. Example of JBoss EAP LDAP login module configuration

 <security-domain name="ispn-secure" cache-type="default">
                  <authentication>
                     <login-module code="org.jboss.security.auth.spi.LdapLoginModule" flag="required">
                        <module-option name="java.naming.factory.initial" value="com.sun.jndi.ldap.LdapCtxFactory"/>
                        <module-option name="java.naming.provider.url" value="ldap://localhost:389"/>
                        <module-option name="java.naming.security.authentication" value="simple"/>
                        <module-option name="principalDNPrefix" value="uid="/>
                        <module-option name="principalDNSuffix" value=",ou=People,dc=infinispan,dc=org"/>
                        <module-option name="rolesCtxDN" value="ou=Roles,dc=infinispan,dc=org"/>
                        <module-option name="uidAttributeID" value="member"/>
                        <module-option name="matchOnUserDN" value="true"/>
                        <module-option name="roleAttributeID" value="cn"/>
                        <module-option name="roleAttributeIsDN" value="false"/>
                        <module-option name="searchScope" value="ONELEVEL_SCOPE"/>
                     </login-module>
                  </authentication>
                </security-domain>

Example 8.3. Example of JBoss EAP Login Module Configuration

<security-domain name="krb-admin" cache-type="default">
                    <authentication>
                        <login-module code="Kerberos" flag="required">
                            <module-option name="useKeyTab" value="true"/>
                            <module-option name="principal" value="admin@INFINISPAN.ORG"/>
                            <module-option name="keyTab" value="${basedir}/keytab/admin.keytab"/>
                        </login-module>
                    </authentication>
                </security-domain>
When using GSSAPI authentication, this would typically involve using LDAP for role mapping, with JBoss EAP server authenticating itself to the LDAP server via GSSAPI. For more information on how to configure this, see the JBoss EAP Administration and Configuration Guide.
