Introduction. This document covers setup of a Squid Proxy which will seamlessly integrate with Active Directory using Kerberos, NTLM and basic authentication for clients not authenticated via Kerberos or NTLM. Authorisation to use the internet is managed by Security Groups in Active Directory by means of LDAP lookup. It is capable of using block and allow lists for site access and restrictions and an optional monitoring section that uses Cyfin Reporter for proxy monitoring. This guide is an expansion and update to a guide I submitted on Howto. Forge and contains some fixes to issues discovered and amendments to incorrect information. I want to take the opportunity at the start of the guide to thank the Squid developers and the support I received on the mailing list in getting this guide completed. Squid Rules Example Environment. For this guide the following examples are utilised you should update any HIGHLIGHTED TEXT sections with your clients domain, hostnames, IPs etc. Domain example. local. Subnet 1. 92. 1. IP 1. HOSTNAME squidproxy. Kerberos computer name SQUIDPROXY K. Windows Server 1. IP 1. 92. 1. 68. HOSTNAME dc. Windows Server 2. IP 1. 92. 1. 68. HOSTNAME dc. Specifications. Most situations will require the proxy to be set up as Debian 6 virtual machine and this guide assumes the use of Debian, Our typical deployment is around 5. GB Virtual Disk. 1. MB RAM this may be reduced if not using Cyfin Reporter. Tip Consideration should be made for creating a separate volume to mount opt. This is where Cyfin Reporter is installed. Prerequisites. Client Windows Computers need to have Enable Integrated Windows Authentication ticked in Internet Options Advanced settings. DNS Configuration. On the Windows DNS server add a new A record entry for the proxy servers hostname and ensure a corresponding PTR reverse DNS entry is also created and works. Check that the proxy is using the Windows DNS Server for name resolution and update etcresolv. Edit the file according to your network. Ping a internal and external hostname to ensure DNS is operating. PING dc. 1. example. PING google. com 7. Check you can reverse lookup the Windows Server and the local proxy ip from the Windows DNS.

Warning If either lookup fails do not proceed until fixed or authentication may fail. NTP Configuration. Because Kerberos needs to have the time syncronised with Windows Domain Controllers for authentication we configure the proxy to obtain time from them. Locate the following section and update the ntp servers as required. If you have more than one Domain Controller or NTP Server you may add multiple lines. You do need to talk to an NTP server or two or three. Restart and test NTP. Run the following ntpq command, you should see output that refers to the Domain Controllers and other NTP Servers which are processed in the order that they appear in the conf file. LOCL. 1 u 3.

Some applications cannot use Kerberos and need to rely on NTLM notably i. Tunes. A problem also exists in the order in which the authentication helpers are used, one example is when using IE on a non domain computer it will fail to negotiate kerberos and will not failover to NTLM or basic authentication, this is regardless of the order in which the helpers are provided. Meaning the user will endlessly receive a popup window requesting authentication. See this link and this link for further information. Thankfully squid developer Markus Moeller created a negotiate wrapper around the Kerberos and NTLM helpers that resolves this. Kerberos. Kerberos utilises msktutil an Active Directory keytab manager I presume the name is abbreviated for Microsoft Keytab Utility. We need to install some packages that msktutil requires. To make the following code easier to copy and paste run the following command, subsitute the MSKTARCH variable with i. MSKTARCHamd. 64. Then obtain the msktutil package and install it. O varcacheaptarchivesmsktutil0. MSKTARCH. deb http fuhm. MSKTARCH. deb. dpkg i varcacheaptarchivesmsktutil0. MSKTARCH. deb.

Warning There are 2 important caveats in regard to the msktutils computer name argument. See this link and this link for further information. NTLM and Kerberos do not conflict, see this link for further information. Vector Eye. This guide uses k appended to the hostname. Execute the msktutil command as follows.
