Ever start building an application with a particular user provider, then change your mind later on? How do you get those users you already made moved from one user provider to another? This little application does it. You need to go tenant-by-tenant, the UI is crude, but it works. Maybe a later version will allow a bulk select.
Corrected a number of minor bugs, improved usability by filtering out the default tenants for espaces and tenants associated with deleted espaces. Made secure for production environments by setting the user provider to Service Center and requiring a login to access.
