FreeRADIUS and LDAP

[jamespedersen-brightpattern.com]

With the FreeRADIUS package, can I use Google Authenticator as a second factor and LDAP authentication as the first factor?

Can the FreeRADIUS package's OTP functionality pull the user's pin and initial secret from the LDAP server? So that I can set the pin and secret in the LDAP server and not have to manage a separate database of users on the Netgate appliance?
