Hi,
I noticed a few people have downloaded my logs - has anyone found
anything useful? It does appear to be a bug to me, but if it is a change
in behaviour I'd be happy of any hints to fix my config.
All the best
Alex
Further to my original post, I've found that NTLM auth does not work
with CONNECT requests from clients in 3.2. I use a similar config to
that I'm using in production in 2.7.
I have disabled ssl-bump and dynamic SSL until I can resolve this.
I do *not* have to add http_access allow CONNECT before http_access
deny CONNECT !SSL_ports in my production config, which seems correct
as otherwise unauthorised users could use CONNECT.
Here is the config I am testing, which works fine for plain HTTP traffic:
auth_param ntlm program /usr/bin/ntlm_auth
--helper-protocol=squid-2.5-ntlmssp
auth_param ntlm children 30
auth_param basic program /usr/bin/ntlm_auth
--helper-protocol=squid-2.5-basic
auth_param basic children 30
auth_param basic realm Squid proxy-caching web server
auth_param basic credentialsttl 2 hours

However CONNECT requests do not work, the client sits forever waiting
for data while squid does not match against AuthorizedUsers and
attempts to return an error page:

Any help much appreciated.
