corda - how to implement corda accounts in a node?

I am using Corda Version 4.

My CorDapp has four nodes - Notary node (validating), "Node A", "Node B" and "Node C".

Node A and Node B are to be designed as private nodes, being accessible to one user each. Node C is a public node, accessible to 5 users.

From documentation in URL "https://github.com/corda/accounts", I understood that by using Corda Accounts the Node C can partition the vault into 5 subsets, where each subset represents an account or user.

To achieve this should I define accounts in node configuration in build.gradle? Is there any example in the git?

  1. RPC users are defined inside node.conf, where the user is able to connect to the node and call flows.
  2. Accounts is something different, before Corda 4.3 a state would be owned by a party/node so for every user you had to have a node, with Accounts library they introduced a stated called AccountInfo which has a host field which is the node that hosts the account, UUID field (unique on network level), and name field (sort of a username) which is unique on host level (i.e. you can create an account devman on NodeA and account devman on NodeB and they are considered different).

Anyway, there are a lot of concepts in the Accounts library and it's not possible to answer them here, have a look at the IOU example using accounts: https://github.com/opticyclic/corda-accounts-demo
Also the library itself has 3 examples, I recommend looking at the GoldTrading one since it's the most simple one.
