Local users may 'break' in that circumstance if:

- they are not in the DB with other users

- a router exists that:

--- precedes the DB-dependent router

--- references ~/etc/master.passwd, shadow password file, or
equivalent shell-account-holder DB's

One can modify such routers to reference the desired DB,
re-order them, remove them, or even deny messaging capability
outright to most shell account holders, which we do also. They
have to use a 'conventional' account and external MUA.
