Firefox 51.0a2 macOS - Error 401 with apache auth ldap

more options

Firefox Developer Edition 51.0a2 won't work with apache auth ldap (v2.2.14, and v2.4.7). Any intranet resource that uses this authentication method will display a 401 in Firefox right away and work fine in other browsers (the standard auth dialog would pop-up).

I have tried fiddling with about:config settings and clearing my cache with no luck. Can this be fixed or has this feature be turned off in the 51 release?
