Unauthorized: {"error":"unauthorized","reason":"You are not a db or server admin."}

edit

I'm following this tutorial .When i try to upload a bag file using:

 rosrun object_recognition_capture upload -a 'asaad' -e 'myemai@email.com' -i silk.bag -n 'silk' -d 'Silk brand soy milk.' --commit milk, soy, kitchen, tod

i get the following error:

Unauthorized: {"error":"unauthorized","reason":"You are not a db or server admin."}

I'm not very familiar with couchDB so please bear with this question( which i know is of a very basic nature). The same happens when i try:

rosrun object_recognition_core push.sh

or any other such command related to COuchDB, for that matter.

I'm using Ubuntu 12.04 & ROS Hydro.
