After attending several security talks the last couple of days, I've 
become rather sensitized to this kind of issue.  I feel quite strongly 
that we should never allow the password to be written to history in 
plain text.   I'm also afraid it could cause us to flunk government 
certifications.

On Windows, this really isn't a problem because command history is not 
saved.  After a CMD session ends, the history is lost (unless you 
install some third-party tool).

Perhaps there is a way to temporarily disable logging of command history 
in the add-user-keycloak.sh?
