javax.jms.JMSSecurityException: User null is NOT authenticated

[Rajesh MadhanGopal]

I am getting the "User null is NOT authenticated" exception in JBoss after migrating from HSQLDB to Mysql for JBoss Messaging.


Configuration details:
JBoss Server 5.1 (4 node cluster)
Mysql 5.5

Heres what i did to migrate from HSQLDB to Mysql:

1. Copied the Mysql JDBC driver (mysql-connector-java-5.1.1.4-bin) to the lib folder of the nodes in JBoss.
2. Replacde the file hsqldb-ds.xml with mysql-ds.xml in the deploy folder in JBoss.
3. Replaced the file hsqldb-persistence-service.xml with mysqldb-persistence-service.xml in the messaging folder under deploy in JBoss.
4. Updated the file mysql-ds.xml to have the following:

                 

<local-tx-datasource>

<jndi-name>defaultDS</jndi-name>

<connection-url>jdbc:mysql://mysql-hostname:3306/jbossdb</connection-url>

<driver-class>com.mysql.jdbc.Driver</driver-class>

<user-name>uname</user-name>

<password>pwd</password>

<transaction-isolation>TRANSACTION_READ_COMMITTED</transaction-isolation>

<min-pool-size>20</min-pool-size>

  <max-pool-size>100</max-pool-size>

<security-domain>MySqlDbRealm</security-domain>


    

5. Uncommented the "guest=guest" entry in the messaging-users file.

6. Added the following in the login-config file present in jboss/conf folder:

              
<application-policy name = "MySqlDbRealm">

<authentication>

<login-module code = "org.jboss.resource.security.ConfiguredIdentityLoginModule" flag = "required">

<module-option name = "principal">uname</module-option>

<module-option name = "userName">uname</module-option>

<module-option name ="password">pwd</module-option>

<module-option name ="managedConnectionFactoryName">jboss.jca:service=LocalTxCM,name=DefaultDS</module-option>

</login-module>

</authentication>

</application-policy>

 

7. Added a reference to the MySqlDbRealm in the mysql-ds file by adding the following:

<security-domain>MySqlDbRealm</security-domain>

8. Ensured that the <type-mapping>mySQL</type-mapping> property vale present in mysql-ds.xml file is the same as the <type-mapping> property in standardjbosscmp-jdbc.xml file.


I am guessing, i am missing some configuration which is causing the issue. Could someone educate me on what needs to be updated to fix this issue. I see a few people have the same issue, but was not able to find a concrete solution or a pointer to the root cause of the issue.

Hi

Could you provide the contents of your standardjbosscmp-jdbc.xml file?

Hi

Is the user 'uname' configured in the database with password 'pwd'?

[Rajesh MadhanGopal]

yes ...thats what i have in the database.

[James Boswell]

I believe I may have found the problem.

Assuming you are using the default server instance in JBoss, there should be a file called messaging-jboss-beans.xml under $JBOSS_HOME/server/default/deploy/messaging. In this file, there is the default configuration for messaging. Something like:

<application-policy xmlns="urn:jboss:security-beans:1.0" name="messaging"> <authentication> <login-module code="org.jboss.security.auth.spi.DatabaseServerLoginModule" flag="required"> <module-option name="unauthenticatedIdentity">guest</module-option> <module-option name="dsJndiName">java:/DefaultDS</module-option> <module-option name="principalsQuery">SELECT PASSWD FROM JBM_USER WHERE USER_ID=?</module-option> <module-option name="rolesQuery">SELECT ROLE_ID, 'Roles' FROM JBM_ROLE WHERE USER_ID=?</module-option> </login-module> </authentication> </application-policy>

This is pointing at the default datasource which assumes to be HSQLDB but which you have now changed to point at your MySQL database. I am assuming the user 'guest' (and probably the tables JBM_USER and JBM_ROLE) cannot be found.

Try turning on debug logging and check the logs just before the exception occurs.

[Rajesh MadhanGopal]

I checked the Mysql Database and saw that both the tables were present and also the user guest was present in those tables, below is the content of messaging-jboss-beans.xml related to messaging.

   <application-policy xmlns="urn:jboss:security-beans:1.0" name="messaging">
      <authentication>
         <login-module code="org.jboss.security.auth.spi.DatabaseServerLoginModule" flag="required">
            <module-option name="unauthenticatedIdentity">guest</module-option>
            <module-option name="dsJndiName">java:/DefaultDS</module-option>
            <module-option name="principalsQuery">SELECT PASSWD FROM JBM_USER WHERE USER_ID=?</module-option>
            <module-option name="rolesQuery">SELECT ROLE_ID, 'Roles' FROM JBM_ROLE WHERE USER_ID=?</module-option>
         </login-module>
      </authentication>
   </application-policy>

[Rajesh MadhanGopal]

Please can someone suggest what might be wrong here?

[Rajesh MadhanGopal]

Hi all,

i finally managed to fix the issue and following is what we did:

Added the below given snippet to the mysql-ds.xml file which does a background check on the connection pool and ensures that there are no stale connection objects in the pool. Apparently, it was the stale connection objects which caused the issue.

<code>
<valid-connection-checker-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLValidConnectionChecker</valid-connection-checker-class-name>
<background-validation-millis>100</background-validation-millis>
<exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter</exception-sorter-class-name>
</code>

Hope this helps some one who has the same issue and wants to know what could fix it.
