Hi Harald,
Thanks for the response. 

we have CLI working perfectly.

For Query:
"Did you set the parameter MemcachedIPv6 to true in your environment files?"
we have passed this in our environment defaults, so yes this is getting passed.

About the Deployment:
3 Node Controller + 1 Compute for the Triple of Stein.
it is working perfectly in the ipv4 segment but when we change the Networking to ipv6 we start seeing this error as reported. 
Please find the attached :
  1. network_data.yaml
  2. roles_data.yaml 
 using these YAML files we are rendering the remaining config files and are using bond-with-vlan configs.

Also for your reference please find the keystone end point details:

Can you share more details from the deployment?
Maby open a bug in Launcpad against TripleO and attach logs, templates
used for deployment, and config files for Horizon?

Did you set the parameter MemcachedIPv6 to true in your environment files?

Does the CLI work?


Regards,
Harald
