Open Stack

For swauth there is provision to change account_id using
swauth-set-account-service, it could be changed to the tenant_id, but since
account_id is part of the hashing, old data in that account won't be
accessible, i am not familiar with keystone, is there any such service in
keystone to change tenant_id, then we can change tenant_id to the
account_id, and old account will be accessible.
