libpam-ldapd and group restriction

Hi,

libpam-ldap had an option to restrict succesful authentications to
members of a vertain ldap group. It's configured with pam_groupdn. I
don't know of an equivalent option for pam_groupdn, however. Is it
possible to limit ldap logins to a select group of people without
locking out local users in case the ldap server goes down (given that
the group is an ldap group and not a local one).
