Comment 6 for bug 675974

I noticed that when trying curl with a sharepoint site it works with older versions of curl!

curl --version
curl 7.21.0 (i686-pc-linux-gnu) libcurl/7.21.0 OpenSSL/0.9.8o zlib/1.2.3.4 libidn/1.18
Protocols: dict file ftp ftps http https imap imaps ldap ldaps pop3 pop3s rtsp smtp smtps telnet tftp
Features: GSS-Negotiate IDN IPv6 Largefile NTLM SSL libz

Here is the command I run when connecting to an exchange server:
curl --ntlm --verbose --show-error --user xxx https://server.com/EWS/Services.wsdl > /tmp/test

Here is the command I run when connecting to a sharepoint server:
curl --ntlm --verbose --show-error --user xxx https://server.com/Lists/Kontakter/AllItems.aspx > /tmp/test

The big differences I notice in the verbose outputs are:
For sharepoint:
Server: Microsoft-IIS/6.0
Content-Length: 1539

For exchange:
Server: Microsoft-IIS/7.0
Content-Length: 0
The string "gss_init_sec_context() failed: : Credentials cache file '/tmp/krb5cc_1000' not found" is shown
The string "WWW-Authenticate: Negotiate" is shown

Also the returned WWW-Authenticate base64 encoded data differs, but maybe the server name in someway is encoded.
