i install horizon and keystone on the same server.Keystone works fine if i use the python-keystoneclient just as follows:

keystone --os-username admin --os-password=keystone --os-tenant-name admin --os-auth-url=http://172.20.9.1:35357/v2.0 user-list

yet after i install horizon and the web shows "An error occurred authenticating. Please try again later" when i set the local_setting.py "OPENSTACK_KEYSTONE_URL=http://172.20.9.1:5000/v2.0/",very weird.

the horizon branch is stable\folsom and python-keystoneclient is of master version. I believe that the trouble must be the communication between horizon and python-keystoneclient,but i don't know how to solve it ,any one has the same situations?
