+If you wish to use Oracle you will need to recompile FreeRADIUS on a machine 
+that has Oracle development libraries installed. FreeRADIUS is known to work both with a full Oracle installation as well as with the [Oracle Instant Client SDK](http://www.oracle.com/technology/tech/oci/instantclient/index.html). Once built the resulting RPM package can be deployed with just the [Oracle Instant Client](http://www.oracle.com/technology/tech/oci/instantclient/index.html) (No need for the SDK on production machines)
+
+Most rpm packages available do not included oraclesql.conf due to the fact that they also don't contain the Oracle driver module (due to copyright restrictions).
+
+If you have the Oracle header files in a sane location it should be a simple matter of taking the latest FreeRADIUS release tarball and 
+dropping it in ``/usr/src/packages/SOURCES`` along with the other files from the ``suse/`` or ``redhat/`` directory inside the tarball with the exception of ``freeradius.spec`` which goes in ``/usr/src/packages/SPECS``
+
+Then edit ``/usr/src/packages/SPECS/freeradius.spec`` and change:
+
+```
+%define _oracle_support 0
+```
+
+to:
+
+```
+%define _oracle_support 1
+```
