Create the initial MES User or OS Group with the minimum required privileges

When the MES Client application is opened for the first time, the login dialog box does not appear because users are not yet defined in the MES database.

The first task you must perform after opening MES Client for the first time is to create a user or OS Group with the following Configurator security privileges enabled:

• May run configuration tools. If this privilege is not enabled, you will not be able to log in to MES Client.

• May edit user settings. If this privilege is not enabled, you will be able to log in to MES Client but you will not be able to create any other users or user groups. You will also not be able to assign entity access to any users.

With these privileges enabled, the initial user or a member of the OS user group can subsequently log into MES Client and other MES applications with configuration privileges.

Note: If the initial user or OS Group is added without the privileges May run configuration tools and May edit user settings enabled, you will have to ask the database administrator to delete the user or OS Group from the users table in the MES database. You can then open MES Client without being prompted to log in and create a user or OS Group with these minimum required privileges.

The procedure you use to create the initial MES user depends on the Security mode you plan to use for MES application user logins. For more information on the available Security modes, see Understand security modes.
