The OpenStack Identity API Version 3 provides support for many features that are not available in version 2. Much of the installer code from Devstack, Puppet Modules, and Packstack, all assumes that Keystone is operating with the V2 API. In the interest of hastening the conversion, I set up a deployment that is V3 only. Here is how I did it.

Automating Kerberos Authentication
Sometimes you need unattended authentication. Sometimes you are just lazy. Whatever the reason, if a user (human or otherwise) wants to fetch a Ticket Granting Ticket (TGT) from a Kerberos Key Distribution Center (KDC) automatically, the Global Security Services API (GSSAPI) library shipped with most recent distributions support it.
Creating Hierarchical Projects in Keystone
Hierarchical Multitenancy is coming. Look busy.
Creating a new Network for a dual NIC VM
I need a second network for testing a packstack deployment. Here is what I did to create it, and then to boot a new VM connected to both networks.

Using the openstack command line interface to create a new server.
I have to create a new virtual machine. I want to use the V3 API when authentication to Keystone, which means I need to use the common client, as the keystone client is deprecated and only supports the V2.0 Identity API.
Horizon WebSSO via SSSD
I’ve shown how to set up OpenStack Keystone Federation with SSSD. We know we can set up Horizon with Federation using SAML. Here is how to set up Web Single Sign On (WebSSO) for SSSD and Kerberos.
OpenStack keeps resetting my hostname
No matter what I changed, something kept setting the hostname on my vm to federate.cloudlab.freeipa.org.novalocal. Even forcing the /etc/hostname file to be uneditable did not prevent this change. Hunting this down took far too long, and here is the result of my journey.

Troubleshooting Keystone in a New Install
Recently heard complaints:
I’ve done a deployment , and every time I try to log in to the dashboard, I get “An error occurred authenticating. Please try again later.” Somewhat surprisingly, the only log that I’m noticing showing anything of note is the Apache error log, which reports ‘Login failed for user “admin”‘. I’ve bumped keystone — where I’d assume the error is happening — to DEBUG, but it’s showing exactly zero activity. How do I go about debugging this?’
Trying to enable LDAP with OpenStack/keystone in Juno release. All the horizon users return error “You are not authorized for any projects.” Similarly, all the OpenStack services are reported not to be authorized.’
What is supposed to happen:
Keystone Federation via mod_lookup_identity redux
Last year I wrote a proof-of-concept for Federation via mod_lookup_identity. Some of the details have changed since then, and I wanted to do a formal one based on the code that will ship for Kilo. This was based on a devstack deployment.
Convince Nova to Use the V3 version of the API
In a recent post I showed how to set up the LDAP in a domain other than default. It turns out that the Nova configuration does accept these tokens; by default, Nova uses the V2 version of the Keystone API only. This is easy to fix.
