( cc-ing you directly since it seems you have trouble receiving mails from the list )

Apologies! My comcast.net account was bouncing mail from the list for reasons unknown. I saw the bounce rating jump from 1 to 3 over the course of this week, so I resubscribed with a proper e-mail address.

Did you read Phil's excellent reply? http://lists.freeradius.org/pipermail/freeradius-users/2013-August/067991.ht...

After Fajar kindly forwarding the link to me, I was able to see the reply. Thanks you, Fajar, and Dan as well. In reviewing your directions, I noticed one configuration missing from my setup: /etc/raddb/sql.conf, $INCLUDE sql/${database}/dialup.conf was commented! I uncommented, re-ran radiusd -X, and saw much more information: # radiusd -X FreeRADIUS Version 2.1.12, for host i386-redhat-linux-gnu, built on Oct 3 2012 at 01:20:08 Copyright (C) 1999-2009 The FreeRADIUS server project and contributors.

So, uncommenting the dialup.conf include appears to have gotten me much further, but radius is still having trouble connecting to the database. A couple things I noted from the above output (which differs from my first posted debug): default_user_profile = "" nas_query = "SELECT id, nasname, shortname, type, secret, server FROM nas" 1. Should I be specifying a default user profile? 2. I don't have a table in my radiusDB called 'nas'. More on PostgreSQL. My /var/lib/psql/data/pg_hba.conf is WIDE OPEN, though it may be missing something more specific (the database is also on localhost): local all all trust host all all 127.0.0.1/32 trust host all all ::1/128 trust It's worth note that I intend to tighten security for the DB once I actually get things working.

It depends on what you need. The defaults work fine for most needs. Just don't break the default configuration (which, from Phil's reply, is exactly what you did).

Yes, it's quite possible I broke something, and thanks so much for your assistance thus far. I have already succeeded in getting FreeRADIUS file-based auth (users) to authenticate Squid users. My goals are: - SSO for Squid and hopefully pptp, using FreeRADIUS auth to authenticate users for these services. - Leveraging PostgreSQL to store user credentials and accounting information for traffic usage. There you have it. Let me know what other information I can provide and hopefully this account won't cause more e-mail delivery/receipt issues. Thanks everyone, MD
