Feature changed by: Duncan Mac-Vicar (dmacvicar) Feature #305546, revision 37 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. Priority Requester: Desirable Projectmanager: Desirable - openSUSE-11.3: Evaluation by product manager + openSUSE-11.3: Rejected by Duncan Mac-Vicar (dmacvicar) + reject date: 2013-03-05 13:24:31 + reject reason: not done Priority Requester: Desirable Package Wishlist: Unconfirmed Priority Requester: Important Requested by: Katarina Machalkova (kmachalkova) Partner organization: openSUSE.org Description: 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) References: https://bugzilla.novell.com/show_bug.cgi?id=440296 https://bugzilla.novell.com/show_bug.cgi?id=412137 Relations: - Cntlm Authentication Proxy (url: http://cntlm.sourceforge.net/) Business case (Partner benefit): openSUSE.org: Significant for adoption in mixed datacenters where the proxy infrastruture is on MSFT assets. Discussion: #1: Federico Lucifredi (flucifredi) (2009-01-26 20:57:23) 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 :-/ #2: Mark Muhlestein (mmuhlestein) (2010-01-13 18:10:39) 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 environment. 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. #3: Katarina Machalkova (kmachalkova) (2010-01-14 15:03:36) 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 (http://curl.haxx.se/docs/comparison-table.html) and it doesn't look too positive :( #4: Duncan Mac-Vicar (dmacvicar) (2010-01-14 16:51:17) 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 http://ntlmaps.sourceforge.net/ 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. #7: Michael Andres (mlandres) (2010-08-10 15:32:24) (reply to #4) Might be worth mentioning that post 11.3 we're about to drop aria2 again. We now have a builtin solution suporting metalink and zync, base on libcurl. #6: Carlo Baffè (cbaffe) (2010-08-05 14:04:03) also Telecom Italia (http://www.telecomitalia.it) asked us about this feature support since their SLES / SMT should pass through MSFT ISA proxies with authentication in order to reach our nu.novell.com. but SLES 11 SP1 does not support it. #9: Andi Chandler (andibing) (2011-12-01 19:58:54) NTLM authentication should be an option in YAST to work seamlessly across all services. #10: Duncan Mac-Vicar (dmacvicar) (2011-12-05 09:27:32) (reply to #9) Has anyone really tried this? I can see in ZYpp code > grep CURLOPT_PROXYAUTH * MediaCurl.cc: SET_OPTION(CURLOPT_PROXYAUTH, CURLAUTH_BASIC|CURLAUTH_DIGEST|CURLAUTH_NTLM ); Which means NTLM is enabled. #12: Michael Calmer (mcalmer) (2011-12-05 10:04:30) (reply to #10) I had this enabled for SMT and a customer was able to authenticate to a proxy.So I went to zypp team and they have enabled this too. I think it is part of 12.1 and Factory, but not on older versions. #17: Michael Andres (mlandres) (2012-06-26 10:24:50) (reply to #12) It's available since 12.1 and in SLES11-SP1 since libzypp-6.37.7 SLES11- SP2 since libzypp-9.11.9 #11: Duncan Mac-Vicar (dmacvicar) (2011-12-05 09:59:45) (reply to #10) Oh, I just realized this commit is only a few days old. This should enable NTLM support, but it needs to be tested. It will be in next openSUSE, SLE service pack or major version. If we need a backport we can do it, but it needs to be tested. commit 3524f4d265a9c697fb201977f60cc7eba3570250 Author: Michael Andres Date: Thu Oct 20 15:57:02 2011 +0200 Set CURLOPT_PROXYAUTH diff --git a/zypp/media/MediaCurl.cc b/zypp/media/MediaCurl.cc index cb27760..901ac45 100644 --- a/zypp/media/MediaCurl.cc +++ b/zypp/media/MediaCurl.cc @@ -620,6 +620,7 @@ void MediaCurl::setupEasy() if ( ! _settings.proxy().empty() ) { SET_OPTION(CURLOPT_PROXY, _settings.proxy().c_str()); + SET_OPTION(CURLOPT_PROXYAUTH, CURLAUTH_BASIC|CURLAUTH_DIGEST| CURLAUTH_NTLM ); /*--------------------------------------------------------------- * CURLOPT_PROXYUSERPWD: [user name]:[password] #13: Yury Krasovski (krasoffski) (2011-12-13 16:06:41) NTLM is very important feature for me, because I have to use proxy with NTLMv2 authentication. I hope, I'll get it in next release, and also I recommend to use a cntlm package. -- openSUSE Feature: https://features.opensuse.org/305546
