You can have multiple authentication databases:-

passdb passwd-file {
    args = /etc/dovecot/special-users

passdb pam {

This works for us when we want to specify proxying, but presumably you'd
need to have some form of password field in "special-users" otherwise.

For userdb, we use passwd-file anyway (PAM can't be a userdb) mainly to
assign uids and gids (though these could be static, of course).

Best Wishes,
