Ceph: how to list all buckets you have access to?

What is the problem you are having with rclone?

I have a Ceph user who is given read access to a number of buckets created by other Ceph users. I cannot list those out using:
rclone lsd k_myreader:

k_myreader is specifically set up as a read-only account. What I really want to do is to list out all bucket sizes that this account has access to, but I cannot even list out the buckets themselves.

If I know the name of a bucket, I can successfully list out things
rclone lsd k_myreader:my_bucket
rclone size k_myreader:my_bucket

Run the command 'rclone version' and share the full output of the command.
