## Description

### Steps to reproduce

1.  Configure an OIDC provider
    
2.  Create a user custom field and make it required
    
3.  Log into OpenProject via OIDC, authenticate with a user that's not yet registered on the OpenProject instance
    

**Alternative:**

1.  Configure an OIDC provider
    
2.  Make sure that the OIDC provider does not fill some required attributes of OpenProject (e.g. username/email)
    
3.  Log into OpenProject via OIDC, authenticate with a user that's not yet registered on the OpenProject instance
    

### What is the buggy behavior?

A registration form is rendered that doesn't make sense for someone logging in via OIDC:

*   It asks to choose a password plus confirmation
    
*   It offers to instead log-in via all of the registered authentication providers
    
*   Even if filling everything out, the registration fails without a meaningful error message
    

### What is the expected behavior?

*   There should be no prompt for a password (because none is needed)
    
*   No authentication providers should be offered (because we already use one)
    
*   Ideally only the required/missing custom fields should be asked for, not any of the other user data that was transmitted from the OIDC provider already
    
*   Filling the form leads to a successful registration and login
