Authentication problem

[Elie Hani]

Hi

I have configured freeradius on Fedora core 6, and using postgresql
database.
I've created also a username locally on the server, defining from which pool
to take it's IP, it works fine, but when I do the necessary changes and
re-do the tests again with a username and password from the database, it
sends the request, but it rejected it. It says login incorrect, eventhough
it has been configured on the database.
The pb is that the server cannot access the database to get the info.

Any idea how to solve it?
Thanks

Elie
