In the url definitions in 

/opt/ocata/ocata/proxy/urls.py and /opt/ocata/ocata/proxy/urlsV1.py (I think this is the one been used)

there is the definition 

urlpatterns = [

1. url(r'^identity/v2)$',
2. identityV2.Tokens.as_view()),
   ...
   url(r'dns-delegate/(?P<requri>[0-9a-zA-Z./_-]*)$',
   dnsaasdelegate.DnsaasDelegate.as_view()),
   url(r'^(?P<servicetype>[0-9a-zA-Z_-]{,18})/(?P<requri>[0-9a-zA-Z./_-]*)$',
   services.Services.as_view()),
   ]

I think the problem is that this is too generic and is been picked up for the wrong requests to the ocata adapter. I think that having the / in the requri sectionis dangerous espically when there is no prefix at the start e.g. like the dns-delegate on the previous line  

this was picked up for the request /api/multicloud-ocata/v1/CloudOwner/regionOne/infra_workload/b4013d57-408e-4a7d-a322-65869c598408/ which then fails due to an autentication problem with the error
