RE: [squid-users] Active Directory.
There are several better options than smb_auth for use against Active Directory: * LDAP (reliable) - The FAQ has info on configuring LDAP helpers * Samba Winbind (a little more complicated - but using NTLM authentication IE users won't need to type in a username/password - it'll pull it directly). Don't forget you need Samba 3. http://itmanagers.net/[EMAIL PROTECTED] has details of getting it going. -Original Message- From: Ampugnani, Fernando [mailto:[EMAIL PROTECTED] Sent: Friday, 19 December 2003 7:00 AM To: [EMAIL PROTECTED] Subject: [squid-users] Active Directory. Hi all, Can squid + smb_auth works with windows 2000 Active Directory.?, If can´t what I might use to authenticate MSAD. Thanks in advance.

RE: [squid-users] winbindd_privileged
This is a Samba and not Squid question..

You're not passing ntlm_auth any configuration options.. It won't know if it's doing NTLMSSP, basic or what..

It's running on a RH9 with samba 3.0. I have winbind working fine with samba but for some reason I just can't seem to get squid to auth with our win2K domain. I keep getting 403 access denied messages. Is there a winbind/ntlm auth configuration guide somewhere ?

RE: [squid-users] SSL Tunnel out-of-box?
It's a little off topic - but I'm wondering why, if you want secure communications between the clients and the Squid server, you aren't thinking of using something like IPsec which *should* provide seamless encryption / data authentication.. Sorry, I can't answer your actual question :) Daniel -Original Message- From: WEHT.net Webmaster [mailto:[EMAIL PROTECTED] Sent: Wednesday, 22 October 2003 11:16 AM To: [EMAIL PROTECTED] Subject: [squid-users] SSL Tunnel out-of-box? Sorry if there are well known answers to this, I've been looking but not finding... Is there a way to get an SSL Tunnel between the client and squid under 2.5.STABLE4 out-of-box (or with a server side patch?) Client --- SSL --- Squid --- Non-SSL/SSL --- Internet My conf is posted below, this works fine via non-SSL between the client-squid (including hitting URI's via SSL on the other side of the squid cache), but when I set my proxy address on the clients to use the SSL port on the squid side, I get this error: Oct 21 21:06:00 sp0090 squid[17038]: clientNegotiateSSL: Error negotiating SSL connection on FD 16: error:1407609C:SSL routines:SSL23_GET_CLIENT_HELLO:http request Which from what I can gather seems to mean the SSL port is getting non-SSL requests from the client. I guess what I'm wondering is if there is a way to do this out-of-box without having to use something like an SSH tunnel from the client side, i.e. convince the web browsers to open SSL connections to the squid cache all the time?

Adam Aube wrote: It's very simple: acl MyDenyMIME urlpath_regex -i \.exe \.mov \.mpg \.mp? you also need $ after the extension That is a good suggestion; though not essential, it does cut down on the false-positive rate. The other downside to a $ on the end means users can stick a ? on the end of most requests to bypass it.. (I use this myself to bypass the block on my own proxy.. Fortunately no one has thought of trying that yet..) Then again - I guess something like urlpath_regex -I \.(exe|mov|mpg|mp?)[?]$ would prob fix that... Daniel

[squid-users] Squid, Samba 3 and NTLM authentication - a walkthrough
Well the Samba 3 full release is just around the corner (or so it sounds from the developers on the samba technical mailing list.) For those of you who are using Win2k+ servers and Squid and want to use Samba 3 and NTLM authentication (for proxy authentication within IE) I have released a Walkthrough with lots of tips and tricks to make the ntlm_auth helper work To grab it head here: http://itmanagers.net/modules.php?name=Newsfile=articlesid=4 (This document is aimed towards people with experience with Samba Squid - but wanting to get ntlm_auth working. Beginners will probably need to refer to Samba Squid docs also). As the Samba 3.0 final is released I will be updating the Walkthough with any changes - so check the page for updates...
