# Account management is tricky. Because we've implicitly committed to

# careful about how we handle cases where networked sources of information

# At the very least, proper handling of password expiration depends on
# this, and in the case of pam_ldap, we also may be depending on the
# directory server for actual "is allowed to log in on this host" data.
# The frequently-suggested method of using pam_localuser to short-circuit
# pam_ldap may be only optional, but we can use pam_succeed_if
# to short-circuit any network checks for *system* accounts
# without allowing actual users in who should be legitimately denied by
# LDAP (if not overriden by enabling the optional pam_localuser).
# Because we'd now be ending the stack with sufficient modules, and PAM's
# behavior isn't defined if none of them return success, we add a
# successful call to pam_permit at the end as a requirement.
