Hi,

Our squid.conf looks like this:
auth_param ntlm program /usr/local/libexec/squid/ntlm_auth --helper-protocol=squid-2.5-ntlmssp -d9
auth_param ntlm max_challenge_reuses 0
auth_param ntlm max_challenge_lifetime 2 minutes
auth_param ntlm children 2

Wonder, even you have done a very detailed report, you don't have read squid.conf comments before .... :-)

From 2.5 STABLE12 squid.conf:
#       "use_ntlm_negotiate" on|off
#       Enables support for NTLM NEGOTIATE packet exchanges with the helper.
#       The configured ntlm authenticator must be able to handle NTLM
#       NEGOTIATE packet. See the authenticator programs documentation if
#       unsure. ntlm_auth from Samba-3.0.2 or later supports the use of this
#       option.
#       The NEGOTIATE packet is required to support NTLMv2 and a
#       number of other negotiable NTLMSSP options, and also makes it
#       more likely the negotiation is successful.

So in squid.conf you need:
auth_param ntlm use_ntlm_negotiate on

Please note:
auth_param ntlm children 2
It is a very too low value, on a loaded proxy you must set this value to a more higher value as 20, 30 or more. You must monitor the helpers usage to find the correct value.

Regards
