There is a nice doc about that here: http://docs.openstack.org/developer/keystone/external-auth.html Note that if you use external_auth as in the example it will only take over the authentication: The user will still need to exist in keystone and roles need to be assigned in the keystone backend. For a "fully integrated” solution you will have to look at LDAP afaik. Cheers, Robert van Leeuwen -------------- next part -------------- An HTML attachment was scrubbed...
