It is usually config-related.

Try these:

• ODC Portal → Users: Test end-user must be active + have EndUser role assigned
• Built-in auth: Password set? (or send invite/reset if SMTP works)
• External IdP: "Sign in as End User" often fails → test via published app instead

Workaround:

1. Create minimal app
2. Publish it
3. Assign EndUser role to user/app
4. Open public URL → log in (try "Continue with Built-in" if email/password fails)

Hello,

There’s documentation that explains how to create a self-registration flow. In ODC, there is a built-in identity provider, unlike O11, which has its own authentication and authorization mechanism.

This means that in O11, you can easily change the username and password, but in ODC things work differently. That’s why I’d recommend trying the self-registration flow approach.

You can refer to these documentations for more details:
