Netbackup Error 99 NDMP Backup Failure

We have a Netapp box which is serving CIFS shares to our clients.

We have faced a  NDMP backup job failure with error code 99.

When opened the failed job detailed status i found it as below.

12/30/2012 10:16:03 PM – Error ndmpagent(pid=7869) ndmp_authenticate_connection: ndmp_connect_client_auth failed 12/30/2012 10:16:03 PM – Error ndmpagent(pid=7869) failed to connect to NDMP server FAS2040 , connect error = -1009 (NDMP server login failed – verify attributes with tpautoconf -verify)

This happened due to i have changed the Netapp ROOT password ( Forget to update the same in Netbackup ) through which Netbackup agent authentication happens to backup CIFS, 

Here is the place we need to change this settings in Netbackup Console.
