In many cases, the site with SSO sets session cookies to keep track of authenticated sessios. Please try enabling cookie jars for LWP::Useragent, to store cookies either by adding 

$ua->cookie_jar({ file => "$ENV{HOME}/.cookies.txt" });

[download]
or 
  require HTTP::Cookies;
  $ua->cookie_jar(HTTP::Cookies->new(file => "$ENV{HOME}/.cookies.txt"
+));

[download]
or even 
  $ua->cookie_jar({}); #this will store cookie in memory. Not in file

[download]
to your code. Enable cookie jar before you send the request.

Hope this helps.
