Bug 1021669

+++ This bug was initially created as a clone of Bug #1021662 +++

Description of problem:

Attempting to configure pulp using the global auth file for yum content:

/etc/pulp/server/plugins.conf.d/yum_importer.json

With either:

{
    "num_threads" : 4,
    "proxy_host" : "http://1.2.3.4",
    "proxy_username": "admin",
    "proxy_password": "redhat",
    "proxy_port" : 8888
}

or


{
    "num_threads" : 4,
    "proxy_host" : "http://admin:redhat@1.2.3.4",
    "proxy_port" : 8888
}


or


{
    "num_threads" : 4,
    "proxy_host" : "http://admin:redhat@1.2.3.4:8888",
    "proxy_port" : 8888
}


Does not seem to work. In most cases I get:

Traceback (most recent call last):
  File "/usr/lib/python2.6/site-packages/pulp_rpm/plugins/importers/yum/sync.py"
, line 109, in run
    metadata_files = self.get_metadata()
  File "/usr/lib/python2.6/site-packages/pulp_rpm/plugins/importers/yum/sync.py"
, line 194, in get_metadata
    raise FailedException(str(e))
FailedException: Proxy Authentication Required


According to my squid log, pulp isn't sending the auth user name

1382375504.460      0 1.2.3.4 TCP_DENIED/407 3969 GET http://lzap.fedorapeople.org/fakerepos/zoo5/repodata/repomd.xml - NONE/- text/html


whereas with curl (passing an incorrect password), i see:


1382375255.594      0 1.2.3.4 TCP_DENIED/407 4105 GET http://lzap.fedorapeople.org/fakerepos/zoo5/repodata/repomd.xml admin NONE/- text/html


Note 'admin' (the user) is missing when pulp tries to access it.

Note that it works fine using curl with the correct password.  

curl -X GET http://google.com/  --proxy http://admin:redhat@1.2.3.4:8888

It very well could be my proxy configuration, however I would expect it to work with basic or digest auth. 



If it 'works', it would be great to get some instructions for setting up a proxy requiring authentication that works with pulp.
