[squid-users] microsoft edge and proxy auth not working

[Rafael Akchurin]

Hello Amos, Markus, all,

Just as a side note - I also suffered  from this error sometime before with Edge and our custom NTLM relay to domain controllers (run as auth helper by Squid). The strange thing it went away after installing some (unknown) Windows update.

I do have the "auth_param ntlm keep_alive off" in the config though.

It all makes me quite suspicious the error was/is in Edge or in my curly hands.

Best regards,
Rafael Akchurin

Try with "auth_param ntlm keep_alive off". Recently the browsers have been needing that.

Though frankly I am surprised if Edge supports NTLM at all. It was deprecated in April 2006 and MS announced removal was being actively pushed in all thier software since Win7.

Not specifically. There should be 1+ for NTLM. Success with NTLM shows
2+. Failure shows 1 or 3 or infinite loop (hello Safari and Firefox 30-ish).

If other software succeeds then the only thing that might be related is the keep-alive option mentioned above. Otherwise the problem is in Edge itself.
