My understanding is you'd have to rely on local accounts or a second
centralized authentication source (probably done via NSS not via
Likewise directly).

Maybe allowing the accounts to float back to AD but somehow restricting
them for Unix login use only...

(We have a long-standing project to migrate off NIS to AD-only --
preserving UID's/GID's and defining the sort of access requirements you
describe is a bit of a challenge).
