Description of problem:
With an existing OSP 10 provider configured, we are attempting to change the service user to an account with rights to more domains/tenants/projects.

With the matching credentials, said user can log in and access Horizon. CF reports bad username or password.

The domain ID is correct ; same result if inputted the domain by name.

DEBUG fog.log output:
