fabric_user (e.g. Fabric User) is a command line application that allows you to add, update, and remove user names and passwords from the user.cfg file. This client automatically updates the user.cfg file version number.

To add, update, or remove a fabric_user, move to a directory other than FABRIC_HOME so you don't accidentally overwrite the user.cfg in that directory. Then retrieve a copy of user.cfg using fabric_ctl. Make the required changes using fabric_user. Redeploy the user.cfg file with fabric_ctl to implement the changes.
