[Ceph Rados Gateway] 403 when using S3 client

Hi All,

I get an http 403 error code when I try to get the bucket list with Ubuntu (Focal) S3 client (awscli).

S3 api has been activated in radosgw config file and EC2 credentials have been created and put in S3 client config file.

Otherwise, everything is working fine with OpenStack client.

My deployment: - OSA 23.2.0 - OpenStack Wallaby - Ceph and Rados GW Octopus

Has any of you already experienced this kind of behaviour ?

Many thanks, Jean-Francois
