Changing the password for derby Admin

Starting from G217, a new user group derbyadmin is defined to manage all connections to the embedded Derby server. By default, the user name is dbadmin and defined in the /var/security/users.properties file. You can easily update the default password manager to any other combinations you like. However, you must follow the steps below to make sure the whole server and relevant database pools work well even after you updated the password.

1. Start Geronimo server
2. Update the password of dbadmin via console >security > Users and Groups portlet
3. Edit the user password in existing datasources via console > Services > Database pools portlet
4. Shutdown Geronimo server
5. Update the userPassword attribute of DerbyNetwork GBean in var\config\config.xml with the new password
6. Restart Geronimo server
