Centralized kerberos authentication

[Sensei]

Hi, I'm back.

I'm trying to set everything step-by-step. The first step is to set up 
an authentication server.

We're using a linux server and a client. Now the client uses pam_krb5.so 
   but I don't know if this is the right way to authenticate over an 
insecure network.

Can you help me? Can you point me to a simple document on this issues?
