Cannot check balance for Calling Card over IVR

If you press 3 in IVR which should tell card owner remaining Card balance and you hear "AUTHORIZATION FAILED" (3 times sometimes)
that means that DB settings are not configured properly in /var/lib/asterisk/agi-bin/mor.conf (should match values in /etc/asterisk/mor.conf)
