Step 1: Installing an enterprise certificate on your computer
The provider of the enterprise certificate (Commfides or Buypass) can support you how to do this.
Step 2: Creating an enterprise user in Altinn
Persons with the role Access manager for the enterprise can register and manage users. They do this under Profile → Advanced settings. In order to register a new user you need to upload the certificate. Make sure it’s a *.cer file. If you haven’t received it from your certificate provider, make it yourself by exporting the certificate from your browser (as long as the certificate has been installed on your PC).
How to create a cer-file in Windows: Press the start button → search for: certificate → select Manage user certificates → select Personal → Certificates → right-click on the certificate → press All tasks → Export → then use the default options in the wizard (next) until you come to filename, choose a name for the file and save it somewhere you can find it again.
Once the enterprise user is created, the general manager or chairman or someone else with delegating rights, give roles and rights to the enterprise user(s).
The roles are given to the user name under Profile → Others with rights to the organization.
