This bug affects lots of other products and prevents us from using curl
to test availability of different web services (affecting zabbix,
nagios, ...).

** Also affects: zabbix (Ubuntu)

Title:
  NTLM authentication isnt tried in libcurl3

Status in “curl” package in Ubuntu:
  Confirmed
Status in “zabbix” package in Ubuntu:
  New

Bug description:
  Binary package hint: libcurl3

  On a fully updated version of Ubuntu 10.10 amd64, under both curl and
  php5-curl, we were unable to use NTLM authentication to talk to our
  exchange server.  Regressing libcurl3 from 7.21.0 to 7.19.5 from
  karmic fixed the problem for both applications.

  Curl verbose log (broken, 7.21.0):
