Hi,

I think I am experiencing a very very similar bug than this one. For GED purposes, we POST documents to a Sharepoint server (so probably similar to Exchange server) through HTTPS and NTLM authentication.

We noticed that for all versions of libcurl >= 7.24 (including the latest version 7.39), it was impossible to POST to this sharepoint server a document larger than ~5MB.

Would you want me to submit an issue here ? I have a complete log file so it may help you figure out what happens exactly.

Thanks !

** [bugs:#1460] Longer Voice Message not being posted to Exchange Server with curl release version >=7.24 using SSL(https)**

Hi Team,
With reference to the following query:
http://curl.haxx.se/mail/lib-2014-12/0011.html
I have written a sample client as a proof of concept that does the POST request for sending a voice message of 5MB.
My application works fine with curl version 7.23.1 while it does not work with 7.24 version.
I have even tried with latest curl version 7.39 but problem is still reproducible.
Attached is sample application code along with 32 bit executable.
Three files are attached in sample_client.zip.
(1) curl-client.cpp
(2) sconstruct   ( sort of makefile )
(3) SampleClient  : ELF 32-bit LSB executable
   Only thing you need is to have 32 bit compiled curl i.e. libcurl.so.4  placed at any Linux box at path /root/
   Try it with different curl versions 7.23.1(works fine) and 7.39 (doesn't work)
 Command Line Arguement for this File
 argv[1] --> Exchange server(2007)  hostname                   :     https://<<hostname>>
 argv[2] --> UserSMTPaddress with Mailbox on Exchange  :     some_user_at_hostname.com
 argv[3] --> PassWord                                                     :     domain\admin:password
  
  How to run:
 ./SampleClient https://hostname.com some_user@hostname.com domain\\admin:password
Here is the Log enabled output for the post request with curl 7.24 ,it just times-out
