Failing to authenticate users

[Phil Mayers]

You've got:

>   modcall[authorize]: module "eap" returns noop for request 0
>     users: Matched entry DEFAULT at line 153
>   modcall[authorize]: module "files" returns ok for request 0

...and

>   modcall[authorize]: module "sql" returns ok for request 0

And finally

>   rad_check_password:  Found Auth-Type System
> auth: type "System"
>   Processing the authenticate section of radiusd.conf
> modcall: entering group authenticate for request 0
>   modcall[authenticate]: module "unix" returns notfound for request 0
> modcall: leaving group authenticate (returns notfound) for request 0
> auth: Failed to validate the user.

Something is setting Auth-Type to "System". It's either the users file 
on line 153, or your SQL. Fix it.
