What configuration file does ocserv read for PAM settings?

[tonytzhou at gmail.com (Tony Zhou)]

Hi,

I am trying to set ocserv up for RADIUS, and I am happy to find out that 
ocserv supports PAM, so I wrote a /etc/pam.d/ocserv like this:

auth    required        /lib/security/pam_radius_auth.so

...But unfortunately it seems ocserv does not like this. What file does 
it read?

Thanks,
TZ
