Sorry, re-post in plain-text.. Hi All, I've been following the guide at this location for Active Directory integration http://wiki.bitbinary.com/index.php/Active_Directory_Integrated_Squid_Proxy First, some versions for sanity.. Ubuntu : 14.04.3 LTS Squid : 3.3.8 (from ubuntu repositories) Samba : 4.1.6-Ubuntu DC : Windows Server 2012 R2 I am currently testing the authentication, negotiate kerberos and basic ldap are both working correctly. However ntlm is not and I don't seem to making any progress on debugging further. Here is the relevant part of squid.conf ### negotiate kerberos and ntlm authentication auth_param negotiate program /usr/lib/squid3/negotiate_wrapper_auth -d --ntlm /usr/bin/ntlm_auth --diagnostics --helper-protocol=squid-2.5-ntlmssp --domain=DOMAIN --kerberos /usr/lib/squid3/negotiate_kerberos_auth -d -s GSS_C_NO_NAME auth_param negotiate children 10 auth_param negotiate keep_alive off ### pure ntlm authentication auth_param ntlm program /usr/bin/ntlm_auth --diagnostics --helper-protocol=squid-2.5-ntlmssp --domain=DOMAIN auth_param ntlm children 10 auth_param ntlm keep_alive off ### provide basic authentication via ldap for clients not authenticated via kerberos/ntlm auth_param basic program /usr/lib/squid3/basic_ldap_auth -R -b "DC=domain,DC=local" -D proxyuser@domain.local -W /etc/squid3/ldappass.txt -f sAMAccountName=%s -h dc1.domain.local auth_param basic children 10 auth_param basic realm Internet Proxy auth_param basic credentialsttl 30 minutes ### ldap authorisation external_acl_type memberof %LOGIN /usr/lib/squid3/ext_ldap_group_acl -R -K -S -b "DC=domain,DC=local" -D proxyuser@domain.local -W /etc/squid3/ldappass.txt -f "(&(objectclass=person)(sAMAccountName=%v)(memberof=cn=%g,OU=Proxy,DC=domain,DC=local))" -h dc1.domain.local With kerberos and ldap working correctly, this seems to cover all my users, except for non-domain joined internet explorer, which unfortunately I still need to cater for. For testing I have allowed the proxy user to login. The following commands work successfully as proxy user wbinfo -p wbinfo -u wbinfo -g wbinfo -t does not run successfully as proxy user, but does run as root. testing ntlm_auth at the command line works correctly. ntlm_auth --helper-protocol=squid-2.5-basic DOMAIN\user password OK When a non-domain joined user with internet explorer attempt to use the proxy, they are continually prompted for credentials.
