dbaccess authentication?

I shared the database installation directory on db1 (IDS 11.50) server through Samba (first time with a password and now opened to everyone - which I am going to change back as soon as I figure out the problem but I did just to avoid an extra step.) I tried to access dbaccess from app1 server through a shell script. (both servers are Red Hat 5). However, I am getting an error: 951: Incorrect password or user dbauser@app1.domain.com is not known onhe database server. the dbauser is basically the DBA of the database but for some reason the database is recognizing it as dbauser@app1 when the script only sends dbauser Here it is the script: INFORMIXDIR=/scratch/informix ONCONFIG=onconfig.wms INFORMIXSERVER=wms_net export INFORMIXDIR ONCONFIG INFORMIXSERVER PATH=$PATH:$INFORMIXDIR/binexport PATH clear while : do echo -e "Enter Container Number or Q to quit:"; read ShipNbr clear if test "$ShipNbr" = "q" then break fi if test "$ShipNbr" = "Q" then break fi . conn.sh dbaccess test_w1 - <<EOF CONNECT USER 'dbauser' USING 'dbapassword'; set isolation dirty read; select b.cont, sum(a.unit_price * b.qty) from od_f a, iv_f b where b.cont ="$ShipNbr" and (a.ob_oid = b.ob_oid and a.ob_type = b.ob_type and a.ob_lno = b.ob_lno) group by b.cont EOF done Any suggestion on how can I authenticate through dbaccess remotely would be helpful. I had the same setup for 9.40 but we upgraded and is not working anymore. Thank you very much,
