Subject [jira] Commented: (GERONIMO-3084) Incompatibilitiy between ActiveMQ JAAS and Geronimo JAAS
Date Fri, 14 Mar 2008 21:24:24 GMT

    [ https://issues.apache.org/jira/browse/GERONIMO-3084?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12578933#action_12578933
] 

David Jencks commented on GERONIMO-3084:
----------------------------------------

Now I looked into this a bit.

IIUC there are no exceptions thrown, the only problem is that activemq doesn't recognize the
principals supplied by a non-activemq login module?

By far the simplest way to proceed here would be to use only the activemq properties file
login module and configure the geronimo security settings for your app to map the jee roles
to those activemq principals.  Geronimo does supply a flexible principal-role mapping for
just such reasons.

There is now a little tiny bit of documentation on the principal-role mapping in g 2.1:

> I have reconfigured Geronimo so that the ActiveMQ broker loads its configuration from
an external XML file.  Within this file, I have specified a security configuration for my
queues and topics.  This is the file:
> ----
> {code}
> <beans>
>   <!-- Allows us to use system properties as variables in this configuration file
-->
>   <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"/>
>   
>   <broker brokerName="localhost" useJmx="true" xmlns="http://activemq.org/config/1.0">
>       
>     <plugins>
>       <!--  use JAAS to authenticate using the login.config file on the classpath
to configure JAAS -->
>       <jaasAuthenticationPlugin configuration="geronimo-admin" />
>       <!--  lets configure a destination based authorization mechanism -->
>       <authorizationPlugin>
>         <map>
>           <authorizationMap>
>             <authorizationEntries>
>               <authorizationEntry queue=">" read="admin" write="admin" admin="admin"
/>
>               <authorizationEntry topic=">" read="admin" write="admin" admin="admin"
/>
>             </authorizationEntries>    
>           </authorizationMap>
>         </map>
>       </authorizationPlugin>
>     </plugins>
>     
>   </broker>
>   <!-- lets create a command agent to respond to message based admin commands on the
ActiveMQ.Agent topic 
>   <commandAgent xmlns="http://activemq.org/config/1.0"/>-->
> </beans>
> {code}
> ----
> As can be seen, I am using the following JAAS login config domain: geronimo-admin.  This
is the standard login domain that gets its users and groups from properties files.  However,
when running the Geronimo server, JAAS cannot matchup the "admin" role specified in the ActiveMQ
XML file with the "admin" role specified in the groups.properties file for the "geronimo-admin"
login domain.  The problem is that the ActiveMQ role is a principal of type {{org.apache.activemq.jaas.GroupPrincipal}},
while the Geronimo JAAS "admin" role is of the type {{org.apache.geronimo.security.realm.providers.GeronimoGroupPrincipal}}.
 Because these principals are different classes, they are not considered "equal" to each other
by the {{equals()}} method on {{org.apache.activemq.jaas.GroupPrincipal}}.  The stack trace
where the error occurs is here:

> Securing the ActiveMQ resources is an important component to securing a production server,
so some way of resolving this issue should be determined.
