Michal Fojtik commented on DTACLOUD-330:
----------------------------------------
Another possible solution for Conductor could be:
* GET /api/drivers
Then parse the response and check if the requested driver is included in list
of driver. This collection does not require authentication, so it should always
return 200.
I'll send a patch for the 401 exception.

> Conductor keeps providers and provider accounts separately. This means that
> at first step a user adds a provider (ec2, rhevm, openstack), then he can add
> multiple accounts for this provider.
> When adding a provider, Conductor checks if the provider is valid by doing dc
> connect with nil credentials:
> DeltaCloud.new(nil, nil, url)
> The problem is that this call always fails for Openstack driver with
> Deltacloud::ExceptionHandler::BackendError - Unhandled exception or status
> code (Must supply a :username):

> From what I know DC requries openstack credentials to be able to connect to
> openstack api and check if some bucket is supported or not.
> Is it possible to offer some unauthenticated connection which can be used
> just to check that a provider is accessible?
