Comment # 2 on bug 1232565 from Stanislav Brabec

Addition to comment 1: It seems to be a behavior change. Even if -A is not
specified, it does not fall back to https://api.opensuse.org:

~> osc -A https://api.suse.de/ ls SUSE:SLFO:Main util-linux
Server returned an error: HTTP Error 401: Unauthorized
~> osc ls openSUSE:Factory util-linux
Server returned an error: HTTP Error 401: Unauthorized
~> osc -A https://api.opensuse.org ls openSUSE:Factory util-linux
