Not able to login to HANA XS application

Hi Experts,

I have developed an HANA XS application to expose the table data using odata services by following the Hana Developer Guide. While executing the application I am getting the login form, but When I enter my credentials, I am getting error saying 'Invalid User name or Password'.

I am sure I am able to login into HANA studio with same credentails.

Could any one please tell me, am I missing any roles or privilages?

Thanks you,
