Hi Adam, We are currently talking to samba, but we are able to join the domain. Where we sit right now is that if we use -basic instead of -ntlmssp it works fine. I've narrowed it down to the password that's the problem - its obtaining the user, domain and workstation just fine. All the command line tools work perfectly - only when using auth_param ntlm * does it fail... As far as I have been able to understand it, there is either a problem with the way squid is passing the reply to the ntlm challenge to the helper, or a problem with the helper... At the moment I'll take any options that are possible... -----Original Message----- From: news [mailto:news@xxxxxxxxxxxxx] On Behalf Of Adam Aube Sent: 09 November 2005 09:12 PM To: squid-users@xxxxxxxxxxxxxxx Subject: RE: Urgent Samba / Squid NTLM Auth Problems Dave Raven wrote: > Okay I have an update with more progress - it seems the problem is > only to do with ntlmssp.

I would suggest taking this to the Samba list. Adam
