Authentication problems between Groovy & CouchDB?

fairly new to Groovy and I've been trying to write some test cases with Groovy for out REST interfaces. To setup our test fixture I needed to clearout the CouchDB databases and wrote a simple script to do this, but for some reason I keep getting Unauthorized messages back from CouchDB. Reduced the code down and still can't see why even though the example script is so simple now. The CouchDB instance has the admin user setup, but that's the only deviation from the default setup. Checked the username/password several times. Annoyingly coping the request from the groovy log and adding 'curl -X ..' works from the cmd line.

@Grab(group='org.codehaus.groovy.modules.http-builder', module='http-builder', version='0.5.0') 
import groovyx.net.http.RESTClient 

RESTClient couchDBRestApi = new RESTClient('http://localhost:5984/') 
couchDBRestApi.auth.basic 'scott', 'tiger' 

['mydb'].each { name -> 
  def resp = couchDBRestApi.delete(path:name) 
  assert resp.status == 200 
}

Looking at the logs I'm worried about a couple of entries in particular the empty list at end of 'WARN DefaultRequestDirector - Authentication error: Unable to respond to any of these challenges: {}' ? and ' DEBUG RESTClient - Response code: 401; found handler: org.codehaus.groovy.runtime.MethodClosure@e2e4d7' ?

full log reads:

Any ideas? doing something stupid? or a bug on someone (who? couchdb or groovy?)

PS No proxies/firewalls/NTLM or anything fancy - all localhost albeit on Windows 7 (development env).

PPS Just quickly tried adding username:password@host to the url - that didn't appear to work either - same error message.

Ok this turns out to be related to a change in CouchDB 0.11 which turns off the basic 401 authentication headers. Now I just need to work out how to turn on pre-authentication for RESTClient/HttpBuilder much like curl does. ref: http://markmail.org/thread/gbky5leiivngglck#query:+page:1+mid:3hraq5ufip2mlpq5+state:results
