Title: Support for NTLM authentication (proxy) in YaST and libzypp

openSUSE-11.2: Rejected by Christoph Thiel (cthiel1)
reject date: 2009-07-16 18:02:44
reject reason: out of context for openSUSE.
Requester: Desirable
Projectmanager: Desirable

- openSUSE-11.3: New
+ openSUSE-11.3: Evaluation
Requester: Desirable

Requested by: Katarina Machalkova (kmachalkova)
Partner organization:

YaST and libzypp should work in an environment with proxy server
requiring NTLM authentication. The feature consists of two parts:
1) YaST proxy module has to provide UI to let user choose NTLM and
write configuration file (/root/.curlrc) accordingly
2) libzypp media backend needs to be adapted to read and understand
such configuration( that is, accept also --proxy-ntlm option instead of
bare --proxy only)


Business case (Partner benefit): Significant for adoption in mixed datacenters where the
proxy infrastruture is on MSFT assets.

Sadly, there is a realistic business case for this in mixed
datacenters. Some odd people like to use NTLM proxies, I will never
understand why.
this will be a headache to do :-/

Many of the engineers at Dell Computer in Austin want to use openSUSE
11.2 on their desktop machines. Dell uses a NTLM proxy on their
corporate network so a lack of this functionality is keeping them from
doing so.
This group of engineers are very loyal SUSE/Novell folks who are trying
very hard to help a SUSE desktop make inroads into Dell's corporate
Current number of engineers who cannot use the product is 50 - 60
On a side note, they see this a glaring problem. I don't know how many
corporations use NTLM proxies but the gents at Dell seem to think it is
quite a lot.

I was wondering whether aria2c can handle NTLM auth. curl certainly
does, but it's not our default downloader anymore. I googled a bit and
found this table ( and
it doesn't look too positive :(

Because we are now using aria2 (however ZYpp stll can fall back to
curl) I asked aria2 author if he planned something in the direction.
He does not, however he will look into the protocol. The problem,
appart of the time, is that he does not have a server to test.
He pointed me to which allows to
authenticate against a NTLM server acting as a normal proxy server. I
have never tested this, but I wonder if companies really need support
for this protocol in the tooling.

#5: Michael Calmer (mcalmer) (2010-01-14 16:57:35) (reply to #4)
I would say yes. I see sometimes logs from the registration where is a
proxy is in use with NTLM authentication. I think this is some kind of
Windows Server which is doing the authentication and automatically
support NTLM. If possible, we should have a way to support this.
