NetBackup Authrization (nbazd) will only be running if you are using NBAC.
If you have not configured NBAC, then I doubt that it is causing any problems.
'waiting in netbackup scheduler work queue on server ' is not an error.
What kind of backup resources have been configured?
In order for job to go active, the Resource Broker needs to find sufficient resources.
Example of resources needed:
Max Jobs per Client
Max Jobs per Policy
MPX in STU
MPX in Schedule
Drives in STU
