PHP - CURL - Microsoft Sharepoint Server 2010 - Authorization

About my server support that i think is relevant
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
PHP Version 5.3.3-7+squeeze3
CURL : 7.21.0
Features
NTLM Yes
Protocols dict, file, ftp, ftps, http, https, imap, imaps, ldap, ldaps, pop3, pop3s, rtsp, scp, sftp, smtp, smtps, telnet, tftp
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

i'm trying to connect to a SharePoint site which requires authorization that, truthfully, i don't know nothing about anymore, it seems like it's modified (same user and pass for all of us, not local, 'remember me' doesn't work)
anyway, i used libcurl many times and had no problem on various sites, and google and documentation say i should have much of a problem now neither

the problem i'm facing is that curl doesn't post, i don't even get an error, php just echoes page back even if i use same code i used on other sites for authentication

(i can provide code i'm using but i don't think that would do much)

so how do i make successful authorization (or even failed post) based on this real request (this is real data made by browser, user and password aren't of course)
this is successful post with source option rather than parsed

Re: PHP - CURL - Microsoft Sharepoint Server 2010 - Authorization

Hi

the problem i'm facing is that curl doesn't post, i don't even get an error, php just echoes page back even if i use same code i used on other sites for authentication

(i can provide code i'm using but i don't think that would do much)

so how do i make successful authorization (or even failed post) based on this real request (this is real data made by browser, user and password aren't of course)
this is successful post with source option rather than parsed

We will need your code to understand your question & request.

Re: PHP - CURL - Microsoft Sharepoint Server 2010 - Authorization

this is the code that works when I use it with other server accessible only from our network (intranet)
------------------------------------------------------------------------------------------------------------------------------------------------------------
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST,  2);
curl_setopt($ch, CURLOPT_COOKIEJAR, "/tmp/cookieFileName");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "j_username=local_username&j_password=local_password");
curl_setopt($ch,CURLOPT_FOLLOWLOCATION,1);
curl_setopt($ch,CURLOPT_MAXREDIRS,10);
curl_setopt($ch, CURLOPT_USERAGENT, 'Opera/9.23 (Windows NT 5.1; U; en)');

curl_exec ($ch); 
------------------------------------------------------------------------------------------------------------------------------------------------------------
but when i change address and  set it to what was in the first message (adress that is accessible from everywhere, everybody can try to login with false data) and test it, the page is then just displayed, nothing happens, no posting as i can see and no errors

so i've tried more and more 
----------------------------------------------------------------------------------------------------------------------------------------------------------------------
$POSTFIELDS = 'ctl00$PlaceHolderMain$login$login=Prijava'; //i've tried with all post fields that are needed but it's the same as with one

$ch = curl_init(); 
    curl_setopt($ch, CURLOPT_URL,$LOGINURL);
curl_setopt($ch, CURLOPT_USERAGENT, 'Opera/9.23 (Windows NT 5.1; U; en)');
    curl_setopt($ch, CURLOPT_POST, 1); 
    curl_setopt($ch, CURLOPT_POSTFIELDS,$POSTFIELDS); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_UNRESTRICTED_AUTH, 1);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
curl_setopt($ch,CURLOPT_FOLLOWLOCATION,1);
curl_setopt($ch,CURLOPT_MAXREDIRS,10);
curl_setopt($ch, CURLOPT_REFERER, $reffer);
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file_path);
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file_path);
curl_setopt($ch, CURLOPT_FAILONERROR, 0);
curl_setopt($ch,CURLOPT_USERPWD,"user:pass"); 
    $result = curl_exec ($ch);
------------------------------------------------------------------------------------------------------------------------------------------------------------

but no luck...of course, i've tried many things, but i fear i'm probably heading in the wrong direction with more options...

------------------------------------------------------------------------------------------------------------------------------------------------------------

Reading/Writing to the same file via FTP...

All I need to do in PHP is:

READ the contents of a file on my FTP server.  (Contents of file are only a single number, 0 - 12)
Add that to a $variable string
Change that $variable and re-write the contents to the same file I READ from.

I am currently READING the contents of the file and adding that to a $variable perfectly using this function:

$expire = "filename";

function read_file($expire)
        {
            $curl = curl_init();
            curl_setopt($curl, CURLOPT_URL, "ftp://"location"/".$expire);
            curl_setopt($curl, CURLOPT_USERPWD, "U:P");
            curl_setopt($curl, CURLOPT_HEADER, 0);
            curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
            curl_setopt($curl, CURLOPT_FRESH_CONNECT, 1);
            curl_setopt($curl, CURLOPT_TIMEOUT, 20);
            $data = curl_exec($curl);
            curl_close($curl);
            if ($data != false){
                return $data;
                }else{
                echo 'ERROR';
               }
        }
            $content = read_file($expire);


As far as WRITING the $new_content variable back to the same file, I am completely lost on finding any examples of this....

My assumption would be:

$expire = "filename";
$content = $new_contents;

function write_file($expire)
           $curl = curl_init();
            curl_setopt($curl, CURLOPT_URL, "ftp://"location"/".$expire);
            curl_setopt($curl, CURLOPT_USERPWD, "U:P");
            curl_setopt($curl, CURLOPT_HEADER, 0);
            curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);

    //this is where I am completely lost...
            curl_setopt($curl, CURLOPT_WRITEFUNCTION, "$new_contents?");
            curl_setopt($curl, CURLOPT_WRITEDATA, "$new_contents?");
    //
            curl_setopt($curl, CURLOPT_FRESH_CONNECT, 1);
            curl_setopt($curl, CURLOPT_TIMEOUT, 20);
            $data = curl_exec($curl);
            curl_close($curl);
            if ($data != false){
                return $data;
                }else{
                echo 'ERROR';
                }
        }


I have read that cURL does NOT need the fopen, fwrite, fclose calls in order to write data to a file? And I have also read about the CURLOPT_WRITEFUNCTION call, and that is where I am not sure how to WRITE the new contents of the $new_contents variable???

A simple example on the cURL PHP example would be wonderful.

I apologize in advance for my lack of PHP or cURL knowledge.  I am working on this project for a commercial business, and I am the smartest one employed here!!

Thanks in advance...
SysAdm

Re: Reading/Writing to the same file via FTP...

You need to write the file on local disk first. Then upload it to ftp.
I have modified your code. See in line bellow.

--- This makes no sense to me that in my PHP that fopen, fwrite and fclose can work on the same file "on the fly" with a simple ftp connection call, but cURL can not? 

The whole reason I'm using cURL is for it's encrypted authentication to the FTP server.  

So basically, if I have to create the file locally with fopen on the client's host machine that is executing my PHP,  then they can just "capture" that file prior to cURL uploading it back to the FTP server?  This is not at all secure for my application.

I was having this done using a simple FTP connection with fopen, fwrite, fclose, but obviously ftp streams the username:password in clear text... again, the whole reason to use cURL. 

Surely there must be a way once I have the "captured" file contents within cURL to overwrite that  data "on the fly" and close the file back.  With nothing being created locally....

Re: Reading/Writing to the same file via FTP...

Write it to php://memory, then pass it to CURLOPT_INFILE as a stream.


If all you're sending is a file containing a number, it would be more straightforward to just set up a basic API on the receiving end and communicate over HTTPS instead of messing with FTP (you're sending the credentials in plaintext even if you're using cURL, unless you're using FTPS).

--- This makes no sense to me that in my PHP that fopen, fwrite and fclose can work on the same file "on the fly" with a simple ftp connection call, but cURL can not? 

The whole reason I'm using cURL is for it's encrypted authentication to the FTP server.  

So basically, if I have to create the file locally with fopen on the client's host machine that is executing my PHP,  then they can just "capture" that file prior to cURL uploading it back to the FTP server?  This is not at all secure for my application.

I was having this done using a simple FTP connection with fopen, fwrite, fclose, but obviously ftp streams the username:password in clear text... again, the whole reason to use cURL. 

Surely there must be a way once I have the "captured" file contents within cURL to overwrite that  data "on the fly" and close the file back.  With nothing being created locally....

Thanks Liu Shan Shui for verifying what I suspected...

I was "assuming" cURL with just FTP access was encrypting the data transit automatically, no need for FTPS or .pem files, or other "handshake" files needed.  I guess I was wrong...

Seems like that would be the next industry standard if someone wrote a lib that "encased" a username:password along transit over HTTP using a simple call... without all the HTTPS, FTPS, needing static IP, etc... etc... hassles...

I ended up going HTTPS, with .htaccess username:password "handshake", then I just used the good old fopen, fwrite, and fclose technique.

Consider this thread SOLVED!

Thanks for everyone's input and ideas....
