[squid-users] problem authentication ntlm with squid 3.5.21

[amaury at tin.it]

Hello
I upgrade squid from 3.4.9-20141203-r13193 to 3.5.21-20160908-
r14081 and I have a problem with authentication to ntlm in a 
transparent configuration:
the squid doesn't switch to https and so it 
doesn't authentication
In my older version the configuration it so:


auth_param basic children 5
auth_param basic realm Squid proxy-caching 
web server
auth_param basic credentialsttl 2 hours

cache_peer xxx.xxx.
xxx.xxx parent 3128 0 no-query no-digest sourcehash name=PRX_ONE

cache_peer yyy.yyy.yyy.yyy parent 3128 0 no-query no-digest sourcehash 
name=PRX_TWO

that it works, but after I upgrade if I use http it 
doesn't autheticate.
Thank you

Best regards,
Mau
