As an update, I think one of my problems was the dangling space after “_member_” in my ACL list, which was quite painful to discover. I think it was breaking the matching of my user, which had the role _member_ assigned.

And, it does look like read ACLs must be of the form “.r:*”, despite the Ceph docs. With this in place, public read ACL works. I still can’t get write ACLs to work though, and from looking at the code[1] I’m not sure how it’s supposed to work.

I have Keystone authentication turned on. Everything works fine in the normal case of creating containers, uploading files, listing containers, etc.
