We'll create fresh WordPress site with OneLogin SAML SSO installed. You have 20 minutes to test the plugin after that site we'll be deleted.
This SAML plugin eliminates passwords and allows you to authenticate WordPress users (typically editors) against your existing Active Directory or LDAP server as well increase security using YubiKeys or VeriSign VIP Access via OneLogin. OneLogin is pre-integrated with thousands of apps and handles all of your SSO needs in the cloud and behind the firewall.
