radiusd.service unit file on ubuntu 16.04

[aquilinux]

Hi all, i'm trying to setup a unit file for radiusd on ubuntu.
radiusd -X starts the server flawlessly, so does /etc/init.d/radiusd start.
no issue at all

I copied radiusd.service from
my /usr/local/src/freeradius-server-3.0.11/redhat over /etc/systemd/system/
but it won't start, complaining about:

Sep 09 15:41:36 miradius04 radiusd[12660]: Could not link driver
rlm_sql_oracle: libclntsh.so.12.1: cannot open shared object file: No such
file or directory
Sep 09 15:41:36 miradius04 radiusd[12660]: Make sure it (and all its
dependent libraries!) are in the search path of your system's ld
Sep 09 15:41:36 miradius04 radiusd[12660]:
/usr/etc/raddb/mods-enabled/sql[20]: Instantiation failed for module "sql"

# locate libclntsh.so.12.1
/usr/lib/oracle/12.1/client64/lib/libclntsh.so.12.1
# env
[..]
ORACLE_HOME=/usr/lib/oracle/12.1/client64
[..]

so I edited the unit file this way:

EnvironmentFile=/etc/default/radiusd

and run systemctl daemon-reload.

the file /etc/default/radiusd contains:

ORACLE_HOME=/usr/lib/oracle/12.1/client64
LD_LIBRARY_PATH=/usr/lib/oracle/11.2/client64/lib

but still radiusd service fails to start.
the message is always "Could not link driver rlm_sql_oracle ..."

i know this isn't a FR question but maybe someone can point me the right
way.

thanks!
