*Security* *NTLMv1 auth has been disabled, NTLM support on non-Windows platforms is now deprecated*
- Bug 828183 ? Firefox enables insecure NTLM (pre-NTLMv2) authentication <https://bugzilla.mozilla.org/show_bug.cgi?id=828183> - Bug 999306 ? Allow generic NTLM v1 if pref set <https://bugzilla.mozilla.org/show_bug.cgi?id=999306> - Bug 1023748 ? Allow NTLMv1 over SSL/TLS, or intranet access is broken on Firefox 30 for non-Windows platforms <https://bugzilla.mozilla.org/show_bug.cgi?id=1023748> The support for the NT LAN Manager version 1 (NTLMv1) network authentication has been disabled because it's known as insecure. Companies and organizations still deploying the older protocol should upgrade to NTLMv2. See Honza Bambas' blog post <http://www.janbambas.cz/ntlm-v1-and-firefox/> and Jason Duell's post to the dev-planning list <https://groups.google.com/d/topic/mozilla.dev.planning/JbrpDmqDLXI> for details. This is affecting SharePoint-based or IIS-backed intranet applications. If you encounter any problems on Firefox 30 or later, you can manually enable NTLMv1 using a preference. Note that NTLMv2 is not supported on non-Windows platforms, so OS X and Linux users have to toggle the preference to continue using NTLMv1 as below, though the NTLM auth support on non-Windows platforms is considered deprecate d. How to enable NTLMv1: type about:config in the location bar, click the "I'll be careful" button, find network.negotiate-auth.allow-insecure-ntlm-v1, double-click on it to change the value to true. You can check to see if NTLMv2 is enabled using the following: https://www.imss.caltech.edu/node/395 On Mon, Jun 16, 2014 at 9:15 AM, Dario Lesca <d.le...@solinos.it> wrote: > After last firefox update the NTLM auth do not work anymore. > > I have download the previous version of FF from Fedora old repo > (firefox-29.0.1-1.fc20.x86_64.rpm) and install it: NTLM auth work. > > (NOTE: "yum downgrade firefox" do not work with this error) > > Resolving Dependencies > > --> Running transaction check > > ---> Package firefox.x86_64 0:25.0-3.fc20 will be a downgrade > > --> Processing Dependency: libxul.so(xul25.0)(64bit) for package: > firefox-25.0-3.fc20.x86_64 > > ---> Package firefox.x86_64 0:30.0-4.fc20 will be erased > > --> Processing Conflict: firefox-25.0-3.fc20.x86_64 conflicts > xulrunner(x86-64) > 25.1 > > --> Finished Dependency Resolution > > Error: firefox conflicts with xulrunner-30.0-1.fc20.x86_64 > > I have also download FF from FF web site and the problem is the same: > FF30 do not work, FF 29 work. > > Some suggest ? > > Thanks > > -- > Dario Lesca > (inviato dal mio Linux Fedora 20 con Gnome 3.10.4) > > > > -- > users mailing list > users@lists.fedoraproject.org > To unsubscribe or change subscription options: > https://admin.fedoraproject.org/mailman/listinfo/users > Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct > Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines > Have a question?
