FreeBSD's openpam doesn't have a built in way of ignoring an unknown
user (e.g. treating PAM_USER_UNKNOWN as a pass for a required module,
like Linux's user_unknown=ignore tag), so there needs to be an
ignore_unknown_user flag built in to the PAM module. This patch makes
pam_sss return PAM_IGNORE instead of PAM_USER_UNKNOWN when
ignore_unknown_user is passed in from the PAM config. FWIW, this is
how pam_ldap works on FreeBSD with local accounts, too.
This patch allows us to keep pam_sss marked as required for the PAM
"account" facility (to enforce HBAC rules) but still allow local users
to log in.
jhrozek suggested posting the patch here for review, so thanks in
advance for looking it over!
