A few things that could be more clear on the installation notes:
4. in login.php search for:
PHP Code:
if ($vbulletin->GPC['vb_login_username'] == '')
{
eval(standard_error(fetch_error('badlogin', $vbulletin->options['bburl'], ....
}
add hook after if statement, becomes:
PHP Code:
if ($vbulletin->GPC['vb_login_username'] == '')
{
eval(standard_error(fetch_error('badlogin', $vbulletin->options['bburl'], ....
}
($hook = vBulletinHook::fetch_hook('ldap_login_hook')) ? eval($hook) : false;
6. in admin cp import the product at "Plugins & Products -> Download / Upload Plugins", use "Import Plugin Definitions XML File" at the bottom of the page, example import input './ldapAuth/ldap-plugin.xml'
