LDAP Authentication Fail with OpenVPN

[ctarbet]

I am using this tutorial: https://helpdesk.sherweb.com/en/support/solutions/articles/67000734003-how-to-configure-a-pfsense-virtual-machine-with-openvpn-and-ldap-authentication

I have LDAP server setup correctly and can use it for pfSense GUI login and Authentication Diagnostics.

When I attempt to use LDAP user with OpenVPN connection, I receive Authentication Failed / User authentication failed.

My OpenVPN connection works perfectly with a regular pfSense local user.

I think that I may not understand which requirements are necessary to connect OpenVPN with the remote LDAP directory as an authentication source.
