After a new installation, the nas probe GUI was taking a very long time to load. Setting the log level to 5 in raw configure and checking the logs, the below is observed:
nas: [last error] thread_id: 49621, error: mysql_real_connect: Access denied for user '<username>'@'xxx.xxx.xxx.xxx' (using password: YES) (errno:1045)
nas: NiS bridge: Failed to initialize database.
