Has anyone been able to script zac commands via remote ssh on SLES 10 Sp2 in ZCM 10.3.1?

This command fails with "error processing zac command"

ssh -n -o StrictHostKeyChecking=no -i /root/xenscripts/identity root@pcaash03.ash.pca.com /opt/novell/zenworks/bin/zac zc

It works fine in a full ssh session.
