User administration

User groups

Access to menu functions is restricted on the basis of three user groups in the operating software.

These groups are automatically set up when you install the software under Windows:

 The user group "DuMaster user" with the lowest authorizations.

 The user group "DuMaster superuser" with more authorizations.

 The user group "DuMaster administrator" with most authorizations.

Allocating users to user groups

The following standard users are automatically allocated to the user groups:

User group

Standard user

DuMaster user DuMasteruser

DuMaster superuser DuMastersuperuser

DuMaster administrator DuMasteradmin

The system administrator must allocate additional individual users via the Windows control panel.

Refer to the Windows help for further information.

Users belonging to multiple user groups

When you log in, the software searches the user groups for the user, starting with the administrator

group. If a user belongs to multiple user groups, he is therefore always offered the higher user group

when he logs in.

Passwords

User passwords must correspond to the usual conventions in Windows. Windows has requirements

regarding:

 The minimum number of characters

 The use of letters, numbers and special characters.

Refer to the Windows help for further information on passwords.

Recommendations for user administration

Recommendations

The following is recommended for user administration:

 In the operating software you should define individual users in addition to the standard users.

Standard users are easuser, eassuperuser and easadmin.

 If you are working with a server, you should not work on one domain only. You should set up an

emergency group on a local computer so that you can also work if the server crashes.

Granting authorizations

Background

The instrument software offers the possibility to assign the access of menu commands to different

user groups, so that individual menus can be invoked only by persons who are authorized

accordingly.
