John,

Thanks for the information. 

When you mention PUT/DELETE accounts - where is this API documented? Or could you provide more details for the supported methods?

Thanks

Divyesh

To provision an account in a swift cluster without using the autocreate option, you must run a proxy server with the allow_account_management option set to True. Your auth system then needs to PUT/DELETE accounts to that proxy server as necessary. There are security implications here (which is why the value defaults to false), so you should take care to ensure that only your auth server can talk to the proxy server with this option turned on.

Essentially, is there any exposed API access for managing accounts in Swift (non-lazy option). The swift_auth.py appears to only handle auth cases including Swift auth but does not actually provide account management (Swift account CRUD).

Would Swift still maintain account information in the db and these will get synchronized with Keystone tenant information (i.e., auto-create accounts), or would Swift get rid of the account concept and have a mapping between tenant and containers instead?  If there is any existing blue-print/docs on Keystone/Swift integration plan for Diablo, that would be greatly appreciated.
