wclient-password not to display as a plain text


Is there a way to display wsclient-password CAF parameter (for a CAF package) value as a set of asterisks instead of displaying the password as a plain text.

This is in our attempt to create a Readonly user (I would say read only admin user) who should be able to login and view all that an Administrator can view… but should not be able modify any configuration / know passwords?
