---------------------------------
> Eucalyptus node driver fails to authenticate on OpenNebula with

> Key: LIBCLOUD-125
> URL: https://issues.apache.org/jira/browse/LIBCLOUD-125
> Project: Libcloud
> Issue Type: Bug
> Components: Compute
> Affects Versions: 0.5.0, 0.5.2
> Reporter: Simon Delamare
> Labels: authentication, ec2
> Fix For: 0.6.0

> Attachments: ec2_sig.patch

> When connecting to OpenNebula through its EC2 compatible interface (using
> libcloud Eucalyptus driver) on a non standard port, the user authentication
> fails.
> Example, with libcloud trunk from git repository:
> $ python
> Python 2.6.6 (r266:84292, Dec 26 2010, 22:31:48)
> [GCC 4.4.5] on linux2
> Type "help", "copyright", "credits" or "license" for more information.

> This is because libcloud never includes the port number after the hostname in
> the authentication signature added to HTTP header. The port number should be
> included if it is non default (!= 80 for HTTP and !=443 for HTTPS). This is
> the standard behavior for HTTP requests (see
> http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.23).
> I am attaching a patch (against git trunk version) that modifies the
> EC2Connection._get_aws_auth_param() function to address the bug. It solves my
> problem:
