[OT] radius, pam and ts

[Vittore Zen]

Hi,

to everyone. I know this is an OT  post but i don't know where post.

I have a freeradius server that's work fine.
I have a tslp that's work fine (with passwd user) (it's and ubuntu
8.04 with ltsp correctly installed)

Now I want use freeradius to autenticate user in tslp desktop.

So, I think to install http://freeradius.org/pam_radius_auth but no
request is sent to freeradius server.

The questions:
1. where install pam_radius_auth? In /etc or in /opt/ltsp/i386/etc?
2. how to configure for ltsp?

Thanks in advance
v.
