I don't know PAM well but I'll make a suggestion stop trying to use it directly and look at sssd its FAR less likely to cause pain and it documentation and logging is far more sane. It might help you stop wasting peoples time asking about software that’s 'using' RADIUS and not actually RADIUS itself. In either case normal refrain, read the documentation provided by the people who wrote the thing you are using (hint that’s not freeradius) and ask them questions if required (again hint not here freeradius != pam).

Please see my other post. The pam module in question is pam_unix.so.

I am new in the Radius concept. So the users in Radius server cannot be processed as those in LDAP because the users in Radius are not configured with UID/GID, etc? On the other hand, Radius cannot completely take the role of LDAP?
So i wonder if PAM is not used for username/ password checking, in that case, Does the UID/GID missing in Radius user matter? In that way, can Radius server replace LDAP?
Thanks again for your advice.
