PROTECTED COMMANDS
Actions on sensible part of the system can be protected by a password. These commands appear on a
window with a user name.If a user has qualified by his name and password the icon on the left side is
turned into green, otherwise it is red. A click on the icon starts an other widow to enter the user name
and password. The password is the normal password of a user, it is checked and if valid the icon becomes
green. Group accounts are not valid user names. This is a general check only. A certain action might be
further restricted to some users only. This is defined on a device basis (or facility) in configuration files.
To disable the password one can push the “disable” button or close the whole ddd application to an icon.
When opening it again the password is cleared.
