I was successful in getting LDAP to work, like so: auth_param basic program /usr/lib/squid/squid_ldap_auth -R -b "dc=domain,dc=com" -D "cn=Administrator,cn=Users,dc=domain,dc=com" -w "password" -f sAMAccountName=%s -h 0.0.0.0 # real IP here auth_param basic children 5 auth_param basic realm SQUID auth_param basic credentialsttl 5 minutes However, this has a login required. I would like to not have this, which I understand is not part of using NTLM. I saw the following on a website: auth_param ntlm program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp auth_param basic program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-basic auth_param basic children 5 auth_param basic realm Squid auth_param basic credentialsttl 2 hours I am receiving some errors. I will investigate more, but does this look correct. I did make the changes to http_access and acl, as requested. Thank you for your assistance.

Further, it looks as though you are trying to perform this query over a non-encrypted channel, which some LDAP servers deny by default. Configuration examples are available for LDAP auth (http://wiki.squid-cache.org/ConfigExamples/SquidAndLDAP) and NTLM (since you have wbinfo working, start at http://wiki.squid-cache.org/ConfigExamples/WindowsAuthenticationNTLM#hea d-ce4db5f4eeb74d1c009e686ce23d633c87300abd). Hope that helps... Chris
