freeradius + oracle for users

Hi,
I'm dealing trying to make freeradius (1.0.1) communicate with oracle 9i
(9.0.2.6) but with no luck at the moment.
I sucessfully compiled the rlm_sql_oracle freeradius module, and also
installed the oracle instant client. Doing an strace of the radiusd program
I see that it finds all files and libraries, but I can't still make the
connection.
Here's the relevant output of radiusd -X:

sql: safe-characters =
"@abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUV WXYZ0123456789.-_: /"
rlm_sql (sql): Driver rlm_sql_oracle (module rlm_sql_oracle) loaded and
linked

rlm_sql (sql): starting 2
rlm_sql (sql): starting 3
rlm_sql (sql): starting 4
rlm_sql (sql): Failed to connect to any SQL server.
Module: Instantiated sql (sql)

I'm still getting the "Couldn't init Oracle OCI environment
(OCIEnvCreate())" error.
Can anyone give me a tip?
Thanks in advance,
