NetBackup 7.6 with NBAC - can't create cron user

I'm trying to get my login to were it's allowed to run commands from cron/bp_start_notify run scripts, but the command to use is giving me an error for which I cannot find any solution for.  In fact I'm having a hard time finding any real documentation on this command:

$ /usr/openv/netbackup/bin/goodies/nbac_cron -setupCron
This application will now create your cron and/or at identity.
Authentication Broker: masterservername.domain.com
Name: myuserid
Password: [masked]
One or more of Name, Password and domain are incorrect

I'm running 7.6.0.3 on RedHat 6.4. I'm able to use the "bpnbat -login" command just fine with the same credentials used in the above command.

Thanks in advance for any help.
