Re: Create and listing topics with AWS4 fails

Hi Daniel,
You are correct, currently, only v2 auth is supported for topic management.
(tracked here: https://tracker.ceph.com/issues/50039)
It should be fixed soon but may take some time before it is backported to
Pacific (will keep the list posted).

Best Regards,

Yuval
