freeradius for pam 1.3.15

[Rachmel, Nir (Nir)]

Hi all!
 
I am using the Radius-Pam module, on an embbeded ppc (windriver linux)
system, and I have a question.
 
I have noticed, that when configuring my box with a DNS server, then
once a user attempts login, a call is attempted at the radius server and
some kind of query is sent to the DNS server.
Looking into the code revealed that there is a call to gethostbyname(),
intended to resolve the ip of myself according to my hostname - or at
least that is what
I could figure out from the available code.
 
Why is it done, and how bad would it be if I changed that call to
something simpler that won't demand a connection to the DNS server?
 
Thanks in advance,
 
Nir Rachmel.
