I am wanting to do Active Directory authentication for my users to gain access to my WordPress website (Private Intranet Type of Site). My Domain Controller (AD LDAP Box) is located on a secure network behind a firewall. Then my websites are located on a hosted platform elsewhere. There is no type of VPN or network to network connection of any sort. I am leary to open my firewall to this type of authentication but know this is the easiest way to authenticate my users without having to setup a new user/password for them. I have looked at the plugins but it seems to me they only will work if they are in the fact on the same network. Any direction is greatly appreciated. I am not a skilled programmer of sorts.
