Authentication

If I want to use MySQL to store the user information, and do not want to
use the 'users' file, I am thinking about using the following configuration.
Since there is no authentication in SQL module, I can only use pap, chap or
unix, etc. right?

authorize
{
  preprocess
  sql
  counter
}

authenticate
{
  authtype PAP
  {
     pap
  }
}

accounting
{
  acct_unique
  detail
  sql
  counter  <----- Do I need this at all?
}

session
{
  sql
}

>From what I understand is that the access request packet will go through the
authorize module first.
SQL can handle that by looking up the User-Name field.  Then authentication
module takes over, where
pap module does the authentication.  But where does PAP find the user
password file?  Does it use the
UNIX /etc/passwd file?
