Hi,

I want to collect windows event logs from a Windows 2008 system via Winrm
webservice on the windows box. I have written service using LibCurl that
subscribes to the Winrm service and then i am able to fetch events from the
source using the same subscription.

I am able to fetch events correctly via Basic authentication using
CURLAUTH_BASIC flag, but i want to use Negotiate authentication protocol, so
when i use CURLAUTH_GSSNEGOTIATE flag i get an error

Negotiate support is enabled on the server. My curl library has
GSS_Negotiate support in it.
C:\pkg\curl-7.22.0-devel-mingw32\curl-7.22.0-devel-mingw32\bin>curl.exe
--version
curl 7.22.0 (i386-pc-win32) libcurl/7.22.0 OpenSSL/0.9.8r zlib/1.2.5
libidn/1.18 libssh2/1.3.0 librtmp/2.3
Protocols: dict file ftp ftps gopher http https imap imaps ldap pop3
pop3s rtmp rtsp scp sftp smtp smtps telnet tftp
Features: AsynchDNS GSS-Negotiate IDN Largefile NTLM SSL SSPI libz

Can you point me the issue there is in this. Do i have to enable any
more flags for this or pass some special headers.
Any help is much appreciated, as i am really stuck in this.

Thanks and Regards
Amit Nanda
