Notes

jdstrand

Keystone on 11.10 is a pre-release version and unusable with other components such as nova and horizon per upstream (and me), change is to intrusive for stable release update and the upstream patch was rejected for Folsom and earlier. This is more of a feature than a vulnerability.
