Hello!
After provider upgraded OpenStack to Queens we have error when try to auth:

Actual(400 Bad Request) (Excon::Error::BadRequest) excon.error.response :body => "{\"error\": {\"message\": \"Invalid input for field 'scope/project/name': 123 is not of type 'string'\\n\\nFailed validating 'type' in schema['properties']['scope']['properties']['project']['properties']['name']:\\n {'type': 'string'}\\n\\nOn instance['scope']['project']['name']:\\n 23446\", \"code\": 400, \"title\": \"Bad Request\"}}" :cookies => [ ] :headers => { "Content-Length" => "326" "Content-Type" => "application/json" "Date" => "Tue, 08 Oct 2019 11:23:47 GMT" "Server" => "Apache/2.4.18 (Ubuntu)" "Vary" => "X-Auth-Token" "X-Distribution" => "Ubuntu" "x-openstack-request-id" => "req-4c4f7e09-d41b-4ad7-85cf-2496cb819b01" } :host => "auth.some.openstack.provider.com" :local_address => "*.*.*.*" :local_port => 59461 :path => "/v3/auth/tokens" :port => 5000 :reason_phrase => "Bad Request" :remote_ip => "*.*.*.*" :status => 400 :status_line => "HTTP/1.1 400 Bad Request\r\n"
