Hi everibody!
    I'v a samba pdc, I'v tried to use squid with ntlmssp to authenticate
but I'v some problem with authentication popup :(, on the cache.log of squid
I see:
  ...
  NTLMSSP challenge
  NTLMSSP challenge
  NTLMSSP Sign/Seal - Initialising with flags:
  NTLMSSP Sign/Seal - using NT KEY
  NTLMSSP OK!
  NTLMSSP Sign/Seal - Initialising with flags:
  NTLMSSP Sign/Seal - using NT KEY
  NTLMSSP OK!
  NTLMSSP NT_STATUS_WRONG_PASSWORD
  NTLMSSP Sign/Seal - Initialising with flags:
  NTLMSSP Sign/Seal - using NT KEY
  ...
why NT_STATUS_WRONG_PASSWORD ?
my portion of smb.conf:
        lanman auth = Yes
        ntlm auth = Yes
        client NTLMv2 auth = Yes
        client lanman auth = Yes
        client plaintext auth = No
        winbind cache time = 15
my squid.conf:
        auth_param ntlm program /usr/bin/ntlm_auth 
--helper-protocol=squid-2.5-ntlmssp
        auth_param ntlm children 5
        auth_param ntlm max_challenge_reuses 0
        auth_param ntlm max_challenge_lifetime 15 minutes
my client are w2k.
francesco.
