getting "authentication required"

[g]

Hi, 

 

I used fiddler composer to send a request from windows machine, but I receive 407, I turned on "auto authenticate" in options. So there is what I see in the sessions window:

session1:

GET http://www.example.com/ HTTP/1.1
User-Agent: Fiddler
Host: www.example.com


HTTP/1.1 407 authenticationrequired
Date: Sat, 14 Jul 2018 07:44:18 GMT
Content-Type: text/html
Cache-Control: no-cache
Content-Length: 12629
Proxy-Connection: Keep-Alive
Proxy-Authenticate: Negotiate
Proxy-Authenticate: NTLM


session2:

GET http://www.example.com/ HTTP/1.1
User-Agent: Fiddler
Host: www.example.com
Proxy-Authorization: Negotiate TlRMTVNTUAABAAAAl4II4gAAAAAAAAAAAAAAAAAAAAAGAbEdAAAADw==


HTTP/1.1 407 authenticationrequired
Date: Sat, 14 Jul 2018 07:44:18 GMT
Content-Type: text/html
Cache-Control: no-cache
Content-Length: 12629
Proxy-Connection: Keep-Alive
Proxy-Authenticate: NTLM
Proxy-Support: Session-Based-Authentication

--------------------------------------------

 

And that's it. How do I make it to go through?

 

Thanks in advance.

Also , here is what I see in the LOG panel:

 

09:44:18:5157 Automatic authentication of Session #12 was unsuccessful. System.Exception AuthenticationManager.Authenticate returned null.

Hi,

When you enable auto authenticate, Fiddler is using the default credentials to authenticate. You can specify username and password to authenticate with as follows:

static function OnBeforeRequest(oSession: Session)
{
   if (oSession.HostnameIs("ServerUsingChannelBinding"))
   {
        oSession["x-AutoAuth"] = "username:MyP@$$w0rd";
   }
}

Hope this helps.
