Matt Darwin [https://community.jboss.org/people/mattdarwin] created the discussion "java.lang.SecurityException: Unauthenticated caller:null when encrypting datasource passwords in AS 5.0.1GA" To view the discussion, visit: https://community.jboss.org/message/723433#723433 -------------------------------------------------------------- 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     org.jboss.security.integration.JBossSecuritySubjectFactory.createSubject(JBossSecuritySubjectFactory.java:92)     org.jboss.resource.connectionmanager.BaseConnectionManager2.getSubject(BaseConnectionManager2.java:687)     org.jboss.resource.connectionmanager.BaseConnectionManager2.allocateConnection(BaseConnectionManager2.java:495)     org.jboss.resource.connectionmanager.BaseConnectionManager2$ConnectionManagerProxy.allocateConnection(BaseConnectionManager2.java:941)     org.jboss.resource.adapter.jdbc.WrapperDataSource.getConnection(WrapperDataSource.java:89)     org.hibernate.connection.DatasourceConnectionProvider.getConnection(DatasourceConnectionProvider.java:92)     org.hibernate.cfg.SettingsFactory.buildSettings(SettingsFactory.java:111)     org.hibernate.cfg.Configuration.buildSettings(Configuration.java:2101)     org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1325)     org.hibernate.cfg.AnnotationConfiguration.buildSessionFactory(AnnotationConfiguration.java:867)     org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:669)     org.hibernate.ejb.HibernatePersistence.createEntityManagerFactory(HibernatePersistence.java:126)     javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:52)     javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:34)     com.mycompany.er.batch.data.DbHelper.createEntityManager(DbHelper.java:30)     com.mycompany.er.batch.data.DbHelper.createAndBegin(DbHelper.java:49)     com.mycompany.er.basman.HibernateTransactionFilter.doFilter(HibernateTransactionFilter.java:53)     org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) |   | I'm trying to encrypt my database password using a JBOSS security domain.
