The yunIO access control allows you to define user authorizations regarding server and yunIO Designer access.


Server Access #

Activate or deactivate access control for the Designer and the server.

  • If Anonymous Access is active, anyone can access the Designer and execute services. This is the default setting.
  • If Authenticated is active, only defined users with a designated restriction level have access to the Designer and the server.
    This option is only available if at least one user is defined and Transport Layer Security is enabled.

Privileges #

Assign restriction levels for Designer and server access to users.

All users defined in User management are listed in Privileges. Select a restriction level from the dropdown list next to the user name to assign a restriction level. The following restriction levels are available:

  • Server Admin: No restrictions.
  • Create / Modify: The user can log in to the designer, can create new connections and services, and can modify existing ones. The user cannot make changes to users, access control, or server settings.
  • Read / Execute: The user can log in to the Designer, but cannot make any changes. The user can run services.
  • No access: The user can neither login to the Designer, nor run any services. This option can be used to temporarily disable users from using yunIO.

How to Restrict Designer and Service Access #

  1. Assign user rights to existing users, see Privileges.
  2. Navigate to Settings and activate Transport Layer Security, see Server Settings: Transport Layer Security.
  3. Restart the yunIO service and connect to the Designer using an HTTPS connection.
  4. Activate Authenticated, see Server Access and restart the yunIO service again.
  5. When connecting to the Designer, you are now prompted to enter user credentials:
  6. Navigate to Services and copy or download a service definition.
  7. Call the service using basic authentication. Enter the credentials of a user that is allowed to run services.

Note: If you get shut out and can’t log in to the Designer, delete the permission.json file in the installation directory of yunIO e.g., C:\Program Files\Theobald Software\yunIO\config\servers\permission.json. Restart the yunIO server.

Tip: You can also use SAP credentials for basic authentication, see SAP Connection: Authentication. Using SAP credentials and custom user credentials for basic authentication in parallel is not supported.
