Re: [squid-users] NTLM Passthru to ISA2006

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

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.
