I think the form I'm trying to log in to is too complex. It's secure, sets three cookies, redirects twice, and posts a number of other variables outside of the username and password, one of which requires a cookie value (I even tried concatenating the value into the post variable, but no luck). This is probably a pretty rare issue - by no means the fault of WKHTMLTOPDF.

I wound up using CURL to log in and write the page to a local file, then ran WKHTMLTOPDF against that. Definitely a solid work around for anyone else having a similar issue.

Edit: CURL, if interested:

curl_setopt($ch, CURLOPT_HEADER, 1); # Change to 1 to see WTF
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
curl_setopt($ch, CURLOPT_URL, $loginUrl);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postFields);
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookie.txt');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
