Hi Amos,
Many thanks for your reply. I have tried changing the config to connection-auth=on but i still get the username/password prompt and even if i enter correct creditials after three attempts the ISA proxy returns an access denied page.
Is there anything else i could be missing?
Many thanks,
Dean

Hi,
Im trying to implement a Squid proxy with a parent of ISA2006 using
integrated NTLM passthru. Should this be possible? I either get three
username/password prompts before i get an authorization required error
message from the ISA server or just a page can not be displayed error?
Any help would be greatly appreciated, this is for a college project.
Many thanks,
Dean Welbourn
What configuration do you have at present? particularly the auth_*,
cache_peer, acl, and http_access lines in the order they appear.
Amos
Ah right. Squid version?
This is only expected to work in Squid-2.6, 2.7, or 3.1.
I have an experiment going with another user at present. The results so
far lead me to believe that cache_peer with NTLM pass-thru can have either
login=PASS - to pass login to backend in Basic format.
or
connection-auth=on - to pass NTLM messages through.
but not both at the same time.
Combining appears to cause multiple-login boxes from the backend which may
not succeed even with correct credentials.
This is not fully confirmed yet, so take it with a very large portion of
doubt. But it may be worthwhile trying the other config.
Amos
I've cc'd you in on the OWA thread where this has had a bit more
permutation testing. Albeit under Squid-3.1.0.3.
It appears to be the same issue and a bug in Squids pass-thru handling.
