curl with ntlm authentication works in command line but not inside php

问题

I have to connect from a Centos Host to a IIS with curl.

Using curl with --ntlm option works fine on the command line, but non in php. Server is a Microsoft IIS and answers first with 401 Unauthorized, on second pass with 200 OK.

After investigating for several hours i did not find a working solution..

When i use curl on the command line (centos 6.4) to retrieve the content of a service:

curl -v http://example.com/do.asmx --ntlm -u DOMAIN\\username:password

the server answers successfully with this code:

* About to connect() to example.com port 80 (#0)
*   Trying nn.nn.nn.nn... connected
* Connected to example.com (nn.nn.nn.nn) port 80 (#0)

ok, so far, this works fine. now i tried to do the same in php :

$ch = curl_init();

curl_setopt( $ch, CURLOPT_URL, 'http://example.com/do.asmx' );
curl_setopt( $ch, CURLOPT_HEADER, true );
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch, CURLOPT_HTTPAUTH, CURLAUTH_NTLM );
curl_setopt( $ch, CURLOPT_USERPWD, "DOMAIN\\username:password" );
curl_setopt( $ch, CURLOPT_TIMEOUT, 10 );
curl_setopt( $ch, CURLOPT_VERBOSE, true );


$output = curl_exec($ch);

print_r(curl_getinfo($ch));
echo curl_error($ch);
curl_close($ch);
var_dump($output);

but nothing happens. the results are

print_r(curl_getinfo($ch)) :

Array
(
    [url] => http://example.com/do.asmx
    [content_type] => 
    [http_code] => 0
    [header_size] => 0
    [request_size] => 0
    [filetime] => -1
    [ssl_verify_result] => 0
    [redirect_count] => 0
    [total_time] => 0
    [namelookup_time] => 0.021611
    [connect_time] => 0
    [pretransfer_time] => 0
    [size_upload] => 0
    [size_download] => 0
    [speed_download] => 0
    [speed_upload] => 0
    [download_content_length] => -1
    [upload_content_length] => -1
    [starttransfer_time] => 0
    [redirect_time] => 0
    [certinfo] => Array
        (
        )

)

echo curl_error($ch) :

connect() timed out!

var_dump($output) :

bool(false)

how could this problem be solved ? this goes beyond my knowledge ..

回答1:

I suggest you remove the base64 strings from the http header Authorization: NTLM TL... since it is possible to decode it and read your domain and credentials exposing you to a huge security risk.

Remove those IP addresses as well unless they are internal only (even still, remove them anyways).

回答2:

First of all, I recommend you to check your security policies. Your firewall can block some packages.
