Does not work with empty secret_key command line parameter

[StefanBrand]

We use radosgw with LDAP: https://docs.ceph.com/en/octopus/radosgw/ldap-auth/

A secret_key is not required and can be left empty. However, s3cmd does not support that. --secret_key must be set to an arbitrary non-empty string.

Note that I don't want to use a config file for easier portability of the command.

Not working

s3cmd ls --access_key=<base64-encoded token> --host=s3.example.com
s3cmd ls --access_key=<base64-encoded token> --secret_key= --host=s3.example.com
s3cmd ls --access_key=<base64-encoded token> --secret_key="" --host=s3.example.com

ERROR: /home/brands/.s3cfg: None
ERROR: Configuration file not available.
ERROR: Consider using --configure parameter to create one.

Working

s3cmd ls --access_key=<base64-encoded token> --secret_key=. --host=s3.example.com
s3cmd ls --access_key=<base64-encoded token> --secret_key=f --host=s3.example.com
s3cmd ls --access_key=<base64-encoded token> --secret_key=foobar --host=s3.example.com
