Firefox authentication: how to enable and configure NTLM

When using IIS, Firefox may ask for user name and password when accessing the QlikView AccessPoint or the QlikView Management Console. 

To use NTLM authentication with Firefox, the preference "network.automatic-ntlm-auth.trusted-uris" needs to be set. This allows Firefox to pass the NTLM authentication information to a web server.

On non-Windows systems, like Linux or Mac: the Access Point may get stuck on "logging in", In that case, NTLM needs to be set to version 1.

Firefox doesn't automatically pass the authentication like IE or Chrome does.
Also, as a part of Firefox 30’s release, Mozilla made a change to disable support for NT LAN Manager version 1 (NTLMv1) network authentication. This change affects sites using Microsoft’s SharePoint or IIS services. The Windows version of Firefox 30 should switch to using NTLMv2 authentication automatically, but NTLMv2 is not supported by Firefox on non-Windows platforms.

On Windows systems:

• Open Firefox and type “about:config” in the address bar. (without the quotes)
• In the ‘Filter’ field type the following “network.automatic-ntlm-auth.trusted-uris” (without the quotes)
• Double click the name of the preference
• Enter the URLs of the sites you wish to pass NTLM authentication to in the form of:
• http://intranet.company.com,http://email.company.lan
• Notice that you can use a comma separated list in this field.
• Close and reopen Firefox: you now should be able to login
   

On non Windows systems (Mac / Linux / Unix) :

• Open Firefox and type “about:config” in the address bar. (without the quotes)
• In the ‘Filter’ field type the following “network.negotiate-auth.allow-insecure-ntlm-v1” (without the quotes)
• Double click the name of the preference. That should change the value from false to true.
• Close and reopen Firefox: you now should be able to login
