Comment 5 for bug 1665543

Well, then tried to set nova_endpoint_admin_template to http://controller00.ostack.fresh:35357/v3 just to see what will happen and it was very close :) The only problem (hmm... at least I think it is) I see my uuid in authentication request instead of name of user:
Member Key: identity
    Object
       Member Key: password
          Object
             Member Key: user
                 Object
..................
                     Member Key: name
                     String value: d........c30494 <- uuid
                     Key: name
