I'm trying to access an armory wallet via RPCs. For instance using the procedure listreceivedbyaddress should ideally return all of the addresses in my Armory wallet. However, when I run this from my shell I get

$ bitcoin-cli listreceivedbyaddress

[ ]

I definitely have addresses inside of my wallet, so I must have some configuration stuff wrong. I let armory start bitcoind on its own, and then I start making calls from bitcoin-cli. Is this the wrong way to use this? I feel like I am missing an authentication step.

Thanks!
