Not returning error on invalid auth

[i0x71]

Is it expected behavior to not return an error on invalid auth credentials ?
I have just spent 10 minutes trying to figure out how come clone makes an empty directory after my commit 😄

i0x71@debian:~$ s3git clone s3://gitty -a 'blah' -s 'blah' -e "http://xxxxxxx:9000"
Cloning into /home/i0x71/gitty
