YUM does not work with proxies who use NTLM

Wirsehark show that yum does not try to use NTLM authentification. Only plain authentification
Steps to Reproduce:
1. Enter proxy parms in the /etc/yum/yum.conf
2. Try to use yum
Authentification fails. Unable to use YUM to manage my platform. No dependency solving
Cross the proxy and let me install additional components.
Since RHEL is targeted at Enterprise and NTLM-based proxies are AFAIK common place this is a critically missing feature, still more since there are distributions (eg Mandriva) who aren't targeting the enterprise and where crossing of NTLM-based proxies works out of the box.
Workaround could be to use local proxy - ntlmaps or cntlm
The proxy solution is not satisfactory:
1) Because cntlm/ntlmaps either plainly not work or because they have huge instability/performance problems
2) Because they are not part of the distribution
I believe this is already requested in RHEL-6 and RHEL-7, and it might get added at some point in RHEL-7 (but I wouldn't guarantee it).
This request was evaluated by Red Hat Engineering for inclusion in a Red
Hat Enterprise Linux maintenance release.
Red Hat does not currently plan to provide this change in a Red Hat
Enterprise Linux update release for currently deployed products.
With the goal of minimizing risk of change for deployed systems, and in
response to customer and partner requirements, Red Hat takes a
conservative approach when evaluating enhancements for inclusion in
maintenance updates for currently deployed products. The primary
objectives of update releases are to enable new hardware platform
support and to resolve critical defects.
