There is currently no way to test anything auth next related in the sandbox mode. The simplest way to support this would be to add capability to generate accounts in the sandbox ledger.
I've just learned that it is possible to emulate this by passing --account flag to the invocation. This is enough for simpler cases, but not for when e.g. we want to do auth for more than a single account.
