Currently trying to authenticate with alfresco 1.11, I'm noticing our deployment doesn't have a /ticket endpoint, but basic auth (as a header for each request) works fine (i.e. via postman). How can I convince alfresco-js to use basic auth per request as a header rather than trying to connect to the ticket endpoint to grab a ticket on .login(username, password)?
