Permission schemes are designed to control access to the software functions
and menus. The permission scheme concept is similar to the usergroup concept
which is used in operation systems to restrict access to certain functions
for a certain group of users. The administrator is able to generate detailed
permission schemes based on the software menus and commands. By assigning
permission schemes to users, different access levels to the software can
be realized. The permission scheme implementation incorporates two separate
The software offers three predefined permission schemes:
Administrator: Access to all security and setup functions.
All other software functions are disabled. The administrator account should
not be used for regular operation of the software.
Power User: Access to all functions of the software
except the security functions.
User: Access to a limited set of functions
In addition to the predefined schemes completely customized permissions
may be defined by the administrator. Permission schemes are designed using
the Permission Scheme Editor and need to be assigned to users using the
command "Assign Permission Schemes" or the User
Management. The Editor looks like this:
The permission scheme editor consists of two main areas:
Shows information about the permission scheme and offers scheme management
Actual Permission Scheme:
Shows the actual permission scheme and allows selection of the scheme
to be edited.
Short description of the permission scheme.
Creates a new permission scheme. All functions will be initially disabled.
Copies the current permission scheme to a different name.
Deletes the current permission scheme.
Resets the permission scheme to the original settings. Changes to a
scheme can be easily undone using the Reset button.
Shows detailed informations about the access rights of the scheme. All
functions of the software are represented by a menu and command listing.
Access rights may be granted or revoked by simply checking or unchecking
the corresponding menu or command.
Access permissions are split into categories. The category Menu contains all regular software functions.
The category Instrument contains
all functions concerning instrument control.
Menu and Command listing:
This is where the actual access rights will be granted or revoked.
The left window lists all available menus. The
right window lists all functions contained in the selected menu. Simply
check the menu/command that is supposed to be available to a user assigned
to the current permission scheme. Checking a menu entry will automatically
activate all commands in that menu. Checking a command will automatically
activate the parent menu if it is not already activated.
With the security functions of the software activated, all users of
the application need to be assigned to a permission scheme. This will
automatically be enforced in the User Management
Dialog. Creating a new user without assigning a permission scheme
is not possible. The permission scheme assignment may be edited later
on using the assignment dialog which looks like this:
The assignment dialog consist of two parts:
Lists all available permission schemes of the application. Select a
scheme to assign new users to it or to unassign existing users.
Shows all users assigned to the current permission scheme and all momentarily
Lists all users that are assigned to the current scheme. To remove
a user from the scheme, select the username and push the button. The username will be added
to the "Available Users" list and can be assigned to a different
scheme by pushing the button
after selecting the new permission scheme.
Lists all user that are temporarily not assigned to a permission scheme.
Users must be unassigned from their current permission scheme by pushing
to be available in this list. All users in this list must be assigned
to a permission scheme before the dialog can be closed. Select the desired
scheme and push the button
to assign the selected user to a new permission scheme.
