Integration Gateway: registering services from ODC

Hi friends,

I registered the standard RMPSAMPLEFLIGHT service in my locally installed SMP Server's Integration Gateway.

Now when I click on 'Service Document' it opens the link in a new tab, and asks for authentication.

It opened http://localhost:8080/gateway/odata/IWBEP/RMTSAMPLEFLIGHT_2;v=1

I see that, neither my SMP credentials nor my Backend credentials are taken. What am I missing?

regards

Krishna
