Firefox and NTLM Authentication

A network I support has a number of Firefox users.  Recently after strengthening their GP settings to enhance security, Firefox users started to experience issues logging in to IIS servers that use intregrated authentication.  This is because by default Digest Authentication is used by FireFox.  In order to enable NTLM authentication in Firefox, I used the information in this link:  http://www.cauldwell.net/patrick/blog/PermaLink,guid,c7f1e799-c4ae-4758-9de7-5c3e7a16f3da.aspx

 

Basically, network.automatic-ntlm-auth.trusted-uris setting in FireFox needs to have the servers listed for which NTLM authentication will be required.

 

If Proxies are required, this setting will be of use:  network.automatic-ntlm-auth.allow-proxies
