the "padmin" utility is not working

Hi All,

I am trying to run the below query in mashzone 10.3 , but getting Authorization error. However the credentials are working fine if I use from browser.

\prestocli\bin>padmin exportDashboard -i “all” -f -l http://localhost:10380 -u Administrator -w manage

log4j:WARN No appenders could be found for logger (
log4j:WARN Please initialize the log4j system properly.
INFO: Authorization failed, please check your username and password combination.

Please help.
