Update enterprise ceritificate

There are two ways to update the certificate on the user:

Option 1 (can only be done before the old certificate expires):
- Log in with the business user here:
https://www.altinn.no/ui/Authentication/EnterpriseIdentified
- Go to Profile -> Login information
- Select "Add certificate" and upload the cer file. See instructions for creating the file further down.

Option 2:
- Log in with a birth number that has the Access Management role.
- Represent the company.
- Go to Profile -> Advanced settings -> Register new user with business certificate.
- Select "Edit user and certificates" to the right of the username. Delete the old certificate (do not delete the user).
- Add the new certificate by uploading the .cer file.
- There is no confirmation, but no error message = OK.

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 comes to filename, choose a name for the file and save it somewhere you can find it again.
