       the area.

        the area.

      Possible Values: warning:   Error-message with list of permissions
                       none:      Nothing is displayed
                       crypt:     RSA-encrpyted text is shown
                       page:      Page in "errorpage" is displayed.
                       text:      Protected text is displayed. With with,
                                  the section is marked as readonly.
errorpage: Page to be shown when show=page is set. 

The text between the opening and closing 'protect'-tags will be hidden for
users not in the specified lists. Members of 'sysop' always have access.

  <protect users="admin1,admin2" groups"sysop">
  Database-Settings
