I've setup RadosGW with STS ontop of my ceph cluster. It works great and fine but
I'm also trying to setup authentication with an OpenIDConnect provider. I'm have a
hard time troubleshooting issues because the radosgw log file doesn't have much
information in it. For example when I try to use the `sts:AssumeRoleWithWebIdentity` API
it fails with `{'Code': 'AccessDenied', ...}` and all I see is the beat
log showing an HTTP 403.
Is there a way to enable more verbose logging so I can see what is failing and why I'm
getting certain errors with STS, S3, or IAM apis?
My ceph.conf looks like this for each node (mildly redacted):
```
[client.radosgw.pve4]
host = pve4
keyring = /etc/pve/priv/ceph.client.radosgw.keyring
log file = /var/log/ceph/client.radosgw.$host.log
rgw_dns_name = s3.lab
rgw_frontends = beast endpoint=0.0.0.0:7480 ssl_endpoint=0.0.0.0:443
ssl_certificate=/etc/pve/priv/ceph/s3.lab.crt
ssl_private_key=/etc/pve/priv/ceph/s3.lab.key
rgw_sts_key = 1111111111111111
rgw_s3_auth_use_sts = true
rgw_enable_apis = s3, s3website, admin, sts, iam
```
