OIDC Integration: Problem Provisioning a Provider via JVM

The Dataverse configuration sets up an OIDC Provider, but it doesn't add a row to authenticationproviderrow, there for the user is not visible in the Dataverse Dashboard ->Manage Users View.

What steps does it take to reproduce the issue?

Step 1: Run the Development Environment

1. Execute npm i.
2. Navigate with cd packages/design-system && npm i && npm run build.
3. Return with cd ../../.
4. Ensure you have a .env file similar to .env.example, with the variable VITE_DATAVERSE_BACKEND_URL=http://localhost:8000.
5. Make sure your dev-env/.env file is filled with the appropriate data. For the REGISTRY variable, please set ghcr.io, as we will use a https://github.com/IQSS/dataverse/pull/10972 dataverse image.
6. Navigate with cd dev-env.
7. Start the environment using ./run-env.sh 10959-bearer-token-auth-ext .
8. To verify the environment, visit http://localhost:8000/ and check your local Dataverse installation.

Step 2: Test the feature in the SPA

1. Click the Log In button in the header.
2. You will be redirected to the Keycloak login page
3. Enter the credentials, there are 4 pre-set users in keycloak, you can log in with any of those users:

• dataverse-user@mailinator.com - pass: user
• dataverse-admin@mailinator.com - pass: admin
• dataverse-affiliate@mailinator.com - pass: affiliate
• dataverse-curator@mailinator.com - pass: curator

4. After the first login, you will be redirected to finish the registration process, where you will have to accept the terms (although there are none for now) and you will also be able to optionally add the affiliation and position.
5. After submitting the form, you will be redirected to the “root” collection page with a welcome success alert and some confetti. 🎉 .
6. After the user has been registered, go to the JSF frontend and login as dataverseAdmin. Go to Dashboard -> Manage Users view. The newly created user is not displayed, only the Dataverse Admin.

An related issue has been created for this in Dataverse: https://github.com/IQSS/dataverse/issues/11090

Start by reviewing the OIDC login and registration flow in the SPA, then verify the resulting user in the JSF Dashboard → Manage Users view. Reproduce with the documented dev-env steps and compare the created user with the related Dataverse issue #11090. Done means a newly registered OIDC user appears in Manage Users.
