    LDAP authentication and Role-based permissions question

    Andrew Cheung Newbie

      Hi. I'm trying to useLdapLoginModule for authenticating into the portal that runs on JBOSS AS 4.0.5GA. The authentication part is ok (the trace logs returns loginOK=true), when I put in the user's username and password in and hit enter. However, in the browser it gives me a 403 error. Error message as follows :

      HTTP Status 403 - Access to the requested resource has been denied

      --------------------------------------------------------------------------------

      type Status report

      message Access to the requested resource has been denied

      description Access to the specified resource (Access to the requested resource has been denied) has been forbidden.


      --------------------------------------------------------------------------------

      Here are the details:

      1. LDAP server (we use eDirectory) :

      Sample user :

      cn=abc,ou=users,ou=MyDivision,o=MyCompany

      Sample Role :

      cn=finance,ou=DistributionLists,ou=MyDivision,o=MyCompany

      The member attribute will contain the users that are assigned to this role.
      For example :

      member=cn=abc,ou=users,ou=MyDivision,o=MyCompany

      2. jboss-4.0.5.GA\server\default\deploy\jboss-portal.sar\portal-server.war\WEB-INF\web.xml :


      <security-constraint>
      <web-resource-collection>
      <web-resource-name>Authenticated</web-resource-name>

      <url-pattern>/auth/*</url-pattern>
      </web-resource-collection>
      <!--<auth-constraint>
      <role-name>Authenticated</role-name>
      </auth-constraint>-->
      <auth-constraint>
      <role-name>finance</role-name>
      </auth-constraint>
      </security-constraint>


      also :

      <login-config>
      <auth-method>FORM</auth-method>
      <realm-name>JBoss Portal</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>Authenticated</role-name>
      </security-role>-->
      <security-role>
      <role-name>finance</role-name>
      </security-role>


      3. jboss-4.0.5.GA\server\default\deploy\jboss-portal.sar\conf\login-config.xml :


      <application-policy name="portal">

      <login-module code="org.jboss.security.auth.spi.LdapLoginModule" flag="required">
      <module-option name="java.naming.factory.initial"> com.sun.jndi.ldap.LdapCtxFactory</module-option>
      <module-option name="java.naming.provider.url">ldap://myLDAPserverIP:389/</module-option>
      <module-option name="java.naming.security.authentication">simple</module-option>
      <module-option name="principalDNPrefix">cn=</module-option>
      <module-option name="principalDNSuffix">,ou=users,ou=MyDivision,o=MyCompany </module-option>
      <module-option name="rolesCtxDN">ou=DistributionLists,ou=MyDivision,o=MyCompany</module-option>
      <module-option name="uidAttributeID">member</module-option>
      <module-option name="matchOnUserDN">true</module-option>
      <module-option name="roleAttributeID">cn</module-option>
      <module-option name="roleAttributeIsDN">false</module-option>
      </login-module>

      </application-policy>


      4. database table "jbp_users" in the portal database :

      The user abc is added to the jbp_users table. The jbp_uid is 11.

      Note : I did not synchronize the passord here from the LDAP server because I thought the password here is not used anymore since we authenticate using the LDAP server


      5. database table "jbp_roles" in the portal datatabase :

      The role "finance" is added to the jbp_roles table. jbp_name and jbp_displayName are both set to "finance". The jbp_rid value is 7.

      6. database table "jbp_role_membership" in the portal database :

      The entry with values jbp_uid = 11 and jbp_rid = 7 is added to the jbp_role_membership table.


      Is any other configurations I need to do in order to make it work?

      Also, is there a way to do more detailed logging so that I can see what's happening after the authentication? Right now the log doesn't show what went wrong regarding to the role permissions.

      Any help is appreciated.

          I just tried your configuration and it seemed to work. Didn't put things into database. Just test if users are authenticated correctly and are able to enter portal.

          I used this
          ldif file and changed:

          1) login-config.xml:

          <login-module code="org.jboss.security.auth.spi.LdapLoginModule" flag="required">
           <module-option name="java.naming.factory.initial">com.sun.jndi.ldap.LdapCtxFactory</module-option>
           <module-option name="java.naming.provider.url">ldap://localhost:10389/</module-option>
           <module-option name="java.naming.security.authentication">simple</module-option>
           <module-option name="principalDNPrefix">uid=</module-option>
           <module-option name="principalDNSuffix">,ou=People,o=test,dc=portal,dc=example,dc=com</module-option>
           <module-option name="rolesCtxDN">ou=Roles,o=test,dc=portal,dc=example,dc=com</module-option>
           <module-option name="uidAttributeID">member</module-option>
           <module-option name="matchOnUserDN">true</module-option>
           <module-option name="roleAttributeID">cn</module-option>
           <module-option name="roleAttributeIsDN">false</module-option>
           <module-option name="searchTimeLimit">5000</module-option>
           <module-option name="searchScope">ONELEVEL_SCOPE</module-option>
           </login-module>
          


          and IdentityLoginModule commented out.

          2) jboss-4.0.5.GA\server\default\deploy\jboss-portal.sar\portal-server.war\WEB-INF\web.xml :
          <security-role>
           <!--<role-name>Authenticated</role-name>-->
           <role-name>User</role-name>
           </security-role>
          
          and
          
          <security-constraint>
           <web-resource-collection>
           <web-resource-name>Authenticated</web-resource-name>
           <description></description>
           <url-pattern>/auth/*</url-pattern>
           </web-resource-collection>
           <auth-constraint>
           <!--<role-name>Authenticated</role-name>-->
           <role-name>User</role-name>
           </auth-constraint>
           </security-constraint>
          


          I'm able to login as admin/admin or as jduke/theduke. Tested with 2.4 and 2.6 trunk

            Andrew Cheung Newbie

            I believe in the configuration that I sent up in my orginal post, the authentication works (otherwise I will get a "login failed" message.) However, it just cannot get to the portal.

            I thought the LDAP server is only used for authentication and not for looking up the role permissions by the portal if I use LDAPLoginModule. Therefore I thought I have to enter into the database the user and the role it is assigned to. Could you please explain in more detail this is not the case?

            Thanks.

              Andrew Cheung Newbie

              Forgot to attach some tracing/logging information in my last reply. Also, our portal is not the default and is accessed by the url : http://localhost:8080/portal/auth/portal/myportal.

              The following is a section of the log starting from the authentication. Any help is appreciated. Thanks.

                I think the reason is:

                2007-03-12 09:55:17,703 DEBUG [org.apache.catalina.realm.RealmBase] Username abc does NOT have role finance

                something in your configuration or LDAP tree must be wrong and 'abc' doesn't get principal 'finance' assigned.

                  Role assignment is also done at the JAAS level. So if you plug different LoginModule portal will see role assignment resolved there and use it to apply security.
