First, agree on a "provider shortname", which will be used to
identify the provider in Argus, e.g. myprovider
This defines the redirect_uri to use: https://portal.mnemonic.no/spa/authentication/openid/provider/myprovider/authenticate
Next, you need to set up Argus as an OpenID Client in your provider:
- Use the redirect_uri above
- Use a random client_id (if not generated by your provider)
- No client secret is necessary, as this is not used in the OpenID
flow used.
