407 Error - How to see the login used ?

[Bob Sauvage <bob.sauvage@xxxxxx>]

Hi *,

I have a problem with a java client. It tries to connect to my Squid 
proxy server with NTLM authentication but a 407 error occurs.

How to see in the squid log the login/(password?)/domain used by the 
java client ? I tried with TCPDUMP but credentials are not displayed.

Thanks in advance,

Cheers,

Bob --
