Troubleshooting PostgreSQL Integration

25 Aug 2013

      Dear Users --

This is my first posting to the FreeRADIUS users list, so please be patient :)

I'm working on an installation of FreeRADIUS which seeks to leverage Postgres as a user store.  Here are the basics of my platform:

- CentOS 6.4 x86
- FreeRADIUS version 2.1.12 w/the following packages installed:

# rpm -qa | grep radius
freeradius-python-2.1.12-4.el6_3.i686
freeradius-2.1.12-4.el6_3.i686
freeradius-postgresql-2.1.12-4.el6_3.i686
freeradius-utils-2.1.12-4.el6_3.i686

- PostgreSQL server v/8.4.13 with the following packages installed:

# rpm -qa | grep postgres
postgresql-libs-8.4.13-1.el6_3.i686
postgresql-8.4.13-1.el6_3.i686
freeradius-postgresql-2.1.12-4.el6_3.i686
postgresql-server-8.4.13-1.el6_3.i686

Before attempting to integrate Postgres into the mix, I confirmed I had a working installation using /etc/raddb/users as a user store:

Output of radiusd -X on startup:

As a sanity check, after making numerous changes to my configs, I reverted back to flatfile based auth by simply reverting the authorization {} section of /etc/raddb/sites-available/default from 'sql' back to 'files'.  Flatfile based auth, as shown above, works great.

Here's the output of radiusd -X startup with 'sql' enabled in /etc/raddb/sites-available/default:

rad_recv: Access-Reject packet from host 127.0.0.1 port 1812, id=60, length=20

I can see from the debug output that it's complaining about the user being invalid.  So here's what my DB looks like:

DBname=# select * from radcheck;
 id |  username   |     attribute      | op |      value       
----+-------------+--------------------+----+--------------------
  1 | radiususer  | Cleartext-Password | := | radiususerPW

DBname=# select * from radreply;
 id |  username   |     attribute     | op |      value      
----+-------------+-------------------+----+---------------------
  1 | radiususer  | Framed-IP-Address | := | MY.PUBLIC.IP.ADDRESS

The schema for this DB was created from /etc/raddb/sql/postgresql/schema.sql.  None of the other .sql files were imported from this directory.  I saw no documentation directing me to do so.

Speaking of schema, I did see one oddity in the /etc/raddb/sql/postgres/dialup.conf which differed from the schema I have.  I attempted making a change to the SQL query in dialup.conf but it did not change the results provided above:

Originally provided in the config:

authorize_check_query = "SELECT id, UserName, Attribute, Value, Op \
  FROM ${authcheck_table} \
  WHERE Username = '%{SQL-User-Name}' \
  ORDER BY id"

Note capitalization of the fields and the order of the fields does not match what I have in my schema.  I changed it to:

authorize_check_query = "SELECT id, username, attribute, op, value \
  FROM ${authcheck_table} \
  WHERE username = '%{SQL-User-Name}' \
  ORDER BY id"

Like I said, nothing changed in the result.  I also changed the SQL statement for authorize_reply_query to reflect the non-caps fields I have as well as the order of the fields.

What else is left to provide as far as details?  Here are my configs themselves.  For ease of communication, I am using 'grep -v '#" to show only the pertinent parts.

Final notes:

- I'm not certain that I'm declaring a default group without PostgreSQL, nor am I aware of how to do this.  
- When reviewing 'man radiusd', I see instructions to edit certain files:

      4) If you need to add a connection to a database FOO (e.g. LDAP or SQL), then:

          a) Edit raddb/modules/foo
          This file contains the default configuration for the module.  It contains comments describing what can be configured,  and  what  those  configuration
          entries mean.

I do not have /etc/raddb/modules/postgresql, or sql.  Which file should I be looking to edit here?

          b) Edit raddb/sites-available/default
          This  file  contains the default policy for the server.  e.g. "enable CHAP, MS-CHAP, and EAP authentication".  Look in this file for all references to
          your module "foo".  Read the comments, and remove the leading hash ’#’ from the lines referencing the module.  This enables the module.

Is this referring to uncommenting 'sql' for authorization?  That's one of the first things I did.

          c) Edit raddb/sites-available/inner-tunnel
          This file contains the default policy for the "tunneled" portion of certain EAP methods.  Perform the same kind of edits as above, for  the  "default"
          file..  If you are not using EAP (802.1X), then this step can be skipped.
          d) Start the server in debugging mode ( radiusd -X ), and start testing.

Apologies in advance if this type of issue has been raised and answered in the past.  The FreeRADIUS wiki's SQL HOW-TO references CentOS version 5.1 which is _years_ old at this point.  Other Google searches and a couple weeks of independent work on the issue have not been helpful.

Thanks in advance for your help.
