    java.lang.SecurityException: Unauthenticated caller:null when encrypting datasource passwords in AS 5.0.1GA

    mattdarwin Newbie

      I'm trying to encrypt my database password using a JBOSS security domain.  I've followed the instructions in the documentation and it all seems pretty simple.  I'm using jboss 5.0.1GA.  It was working fine before I tried to set up password encryption.

       

      The datasource is defined in oracle-ds.xml as follows:

       

      <datasources>
       
      <local-tx-datasource>
         
      <jndi-name>OracleDS</jndi-name>
         
      <connection-url>jdbc:oracle:thin:@dbhost:1521:db</connection-url>
         
      <driver-class>oracle.jdbc.driver.OracleDriver</driver-class>
         
      <!-- app works fine when you use unencrypted password like this
          <user-name>username</user-name>
          <password>unencrypted_pass</password>
          -->

         
      <!-- Use the security domain defined in conf/login-config.xml for username and encrypted password-->
         
      <security-domain>Encrypt-my-Password</security-domain>
      ....etc

       

      The login-config.xml file contains this entry:

         <application-policy name="Encrypt-my-Password">
                     
      <authentication>
                         
      <login-module
                                 
      code="
      org.jboss.resource.security.SecureIdentityLoginModule"
                                 
      flag="required">
                                 
      <module-option name="username">databaseUsername</module-option>
                                 
      <module-option name="password">232487h4873hf4</module-option>
                                 
      <module-option name="managedConnectionFactoryName">jboss.jca:service=LocalTxCM,name=OracleDS</module-option>
                         
      </login-module>
                 
      </authentication>
         
      </application-policy>

       

      As soon as I started using this config the application throws an exception as follows when you try to access the datasource:

      java.lang.SecurityException: Unauthenticated caller:null

      </login-module>
                 
      </authentication>
         
      </application-policy>

      NB the ErSecureIdentityLoginModule is a class already used to encrypt / decrypt DB passwords in another application, where it works fine.

      I downloaded the source code for jboss 5.0.1GA and debugged with TRACE enabled.  There is an interesting stack trace produced:

      The NullPointerException refers to this line of code in org.jboss.resource.security.SubjectActions:


            static class AddPrincipalsAction implements PrivilegedAction
             {
                Subject subject;
                Principal p;
                AddPrincipalsAction(Subject subject, Principal p)
                {
                   this.subject = subject;
                   this.p = p;
                }
                public Object run()
                {
                   subject.getPrincipals().add(p);
                   return null;
                }
             }

      However this doesn't help much, and I can't understand what I'm doing wrong. Help!
