## Interface JDBCUserUtil

-     public interface JDBCUserUtil

  Utility to create users/roles/permissions. This is a helper class and not intended to be a full user management utility. While the standard authentication and authorization interfaces will require usually read only access to the database, in order to use this API a full read/write access must be granted.
