** Description changed: System version: Ubuntu 14.04.4 LTS Squid version: 2:4.3.8+dfsg-0ubuntu0.14.04.2 Winbind version: 2:4.3.8+dfsg-0ubuntu0.14.04.2 upgrade to 2:4.3.9+dfsg-0ubuntu0.14.04.1 My ubuntu server installed Squid to perform http_proxy. Squid auth the - Active Directory users by winbind, settings like follow: + Active Directory users(Win2003) by winbind, settings like follow: ... auth_param ntlm program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp ... Everything is ok until I upgrade winbind from 2:4.3.8+dfsg- 0ubuntu0.14.04.2 to 2:4.3.9+dfsg-0ubuntu0.14.04.1 today. Squid can't auth the AD users anymore. There are some error log in the cache.log: ... 2016/05/05 13:50:45| ERROR: NTLM Authentication Helper '0x7fb54812af68' crashed!. 2016/05/05 13:50:45| ERROR: NTLM Authentication validating user.

And now I downgraded winbind to 2:4.1.6+dfsg-1ubuntu2(I can't downgrade it to 2:4.3.8+dfsg-0ubuntu0.14.04.2, it keeps telling me "Unable to find a version..."), Squid auth_param ntlm works again.
