Hi I've been following this article to setup FreeRADIUS Google Dual Factor Authenticator

http://www.supertechguy.com/help/security/freeradius-google-auth

Hours of testing I still can't get it to work. If my /etc/pam.d/radiusd looks like the following it works well with
the following command

radtest test test localhost 18120 testing123

---
#

```
# /etc/pam.d/radiusd - PAM configuration for FreeRADIUS
#

# We fall back to the system default in /etc/pam.d/common-*
#

@include common-auth
@include common-account
@include common-password
@include common-session
--------------------------------------------------------

However if it looks like the following

--------------------------------------------------------
#
# /etc/pam.d/radiusd - PAM configuration for FreeRADIUS
#

# We fall back to the system default in /etc/pam.d/common-*
#

#@include common-auth
#@include common-account
#@include common-password
#@include common-session

auth requisite pam_google_authenticator.so forward_pass
auth required pam_unix.so use_first_pass
--------------------------------------------------------

my log file says the following and auth fails.
