[Robert Harper] I've been using the MBeanServer to access the tomcat-users database but there are not methods for retrieving the group or role for a user.

User database and user attributes
I am using the Tomcat user database to hold information for users. What I need to do is retrieve the group a user is in from the database.

I often get exceptions thrown when I call the save() method on the user object stating that Tomcat cannot rename the tomcat-users.xml to tomcat-users.xml.old.
