curl sends basic insted of ntlm

dsx has asked for the wisdom of the Perl Monks concerning the following question:

hello guys

i want download a file from a IIS webserver which requires ntlm authentication. but WWW::Curl::Easy sends a basic-authentication-header. what could be the problem?

#!/usr/bin/perl

open(TMPF, ">", "tempfile");
print "User: ";
chomp($user = <STDIN>);
if (system("stty -echo") == 0){
                print "Password: ";
                chomp($pw = <STDIN>);
}else{
                print "stty -echo failed";
                exit 1;
}
system("stty echo");

use WWW::Curl::Easy;
my $curl = WWW::Curl::Easy->new;
$curl->setopt(CURLOPT_URL,'http://ugly_iis/securedoument.txt');
$curl->setopt(CURLOPT_FOLLOWLOCATION,1);
$curl->setopt(CURLOPT_UNRESTRICTED_AUTH,1);
$curl->setopt(CURLOPT_HTTPAUTH,CURLAUTH_NTLM);
$curl->setopt(CURLOPT_USERPWD,$user . ':' . $pw);
$curl->setopt(CURLOPT_FILE,TMPF);
my $retcode = $curl->perform;
close(TMPF);

hy the verbose mode gave me the following error `gss_init_sec_context() failed: : Credentials cache file '/tmp/krb5cc_1000' not found< WWW-Authenticate: Negotiate` seems to be a bug of libcurl if curl is built with NSS insted of OpenSSL. but curl --version gives me `curl --version curl 7.21.0 (i486-pc-linux-gnu) libcurl/7.21.0 OpenSSL/0.9.8o zlib/1.2 +.3.4 libidn/1.15 libssh2/1.2.6 x Protocols: dict file ftp ftps http https imap imaps ldap ldaps pop3 po +p3s rtsp scp sftp smtp smtps telnet tftp Features: GSS-Negotiate IDN IPv6 Largefile NTLM SSL libz` [download] how can i find out wich version of libcurl perl does use?

the problem was a bug in the version 4.12 of the module WWW::Curl which is used in the debian package libwww-perl-curl. the bug is fixed in the recent version of WWW::Curl http://cpansearch.perl.org/src/SZBALINT/WWW-Curl-4.15/Changes	[reply]
