Where do I configure credentials?

Yeah, noob question...

We have IVIM 2.1.1, NPM 11.5.3, SAM 6.2.3, etc and the VMAN appliance. I have integrated them.

There are places to enter ESX credentials in iVIM/Orion and on the appliance.

After reading the Admin Guide, I'm still not clear...

Where do I add the credentials to? To I have to do both sides? Are credentials shared between Orion and the Appliance?

Thanks
