script OK but NTLM authentication problem (“solved”)

Great script, but NTLM problem caused by perlcurl?
I tried to use this script for another website but got AUTHENTICATION FAILED. Using tcpdump showed Basic Authentication. changing the line
$curl->setopt(CURLOPT_HTTPAUTH, CURLAUTH_NTLM);
into
$curl->setopt(CURLOPT_HTTPAUTH, 8);
solved this problem. It seems that the constant CURLAUTH_NTLM has the value 0 in my case instead of 8. On another system with perl-WWW-Curl-4.15-12.el7.x86_64 instead of perl-WWW-Curl-4.09-4.el6.i686 the value of CURLAUTH_NTLM = 8 so the root casus must be in perl-WWW-Curl-4.09-4.el6.i686
Script works fine now
