Open Stack

Hi

I am working on keystone2keystone federatoin and using kilo version for
both keystone-sp and keystone idp
After configuring keystone-sp and keystone-idp I am trying to use the
command :

openstack federation project list -os-auth-type v3unscopedsaml
--os-identity-provider k2k  --os-auth-url https://10.63.13.161:35357/v3
--os-identity-provider-url
https://10.63.13.163:35357/v3/OS-FEDERATION/saml2/idp --os-username user
--os-password password

It returns an error:

ERROR: openstack Expecting to find application/json in Content-Type header
- the server could not comply with the request since it is either malformed
or otherwise incorrect. The client is assumed to be in error. (HTTP 400)
(Request-ID: req-4839f349-e3ed-403f-b456-dfc0d1aecbe4)

This is because in keystoneclient/contrib/auth/v3/saml2.py, while sending a
request to keystone.idp for saml assertion, the content type used is
text/xml

idp_response = session.post(
            self.identity_provider_url,
            headers={'Content-type': 'text/xml'},
            data=etree.tostring(idp_saml2_authn_request),
            requests_auth=(self.username, self.password),
            authenticated=False, log=False)

why is keystone.idp not accepting the content type: text/xml?
what can be the workaroung for this issue

Thanks
