User administration
4.1 Overview
The admin can add/delete users and rights via OPC UA methods provided by the server.
Therefore a connection with a generic client must be established, using the admin credentials.
Users and rights can then be assigned using the following OPC UA server methods:
● Add users (AddUser, AddCertificateUser)
● Delete users (DeleteUser)
● List users (GetUserList)
● Change password (ChangeMyPassword)
● Give access rights (GiveUserAccess)
● Remove access rights (DeleteUserAccess)
● List access rights (GetMyAccessRights, GetUserAccessRights)
NOTICE
Misuse of rights
As an administrator you are fully responsible for the administration of users and their rights.
Any error in the administration process can lead to the misuse of rights.
Note
Anonymous connection
You can also establish an anonymous connection during commissioning, if this setting is active,
but the methods will not be available (feedback: "BadRequestNotAllowed").
Note
Anonymous user
Anonymous users don't have any access (Read/Write) rights after installation. As an
administrator you have to set these rights explicitly.
Note
Administrator has only read rights
Note that the administrator has only read rights per default. Other rights need to be set explicitly.
Note
You can only add/remove users/rights if you are connected as administrator. If you call the
methods with a different user, you will receive the message "BadInvalidArgument".
