Hi Steve,    Thank you for your recommendation. As i was looking through duo security configuration, it seems that the ldap server name is not locked to individual IP. Can this be fixed to individual ip since certain firewall might not control access based on name. Also, must i use duo custom sign-in page in order for this to work?    I believe you may have look at other products before choosing this product.
