The sudoNotBefore and sudoNotAfter attribute support is only used
when ldap.conf enables the SUDOERS_TIMED setting. This is because
those attributes are used directly in the LDAP filter if available.
Your LDAP server must have the updated schema if you want to enable
SUDOERS_TIMED in ldap.conf.
The sudoOrder support does not affect the LDAP filter sudo uses and
so there is no need to explicitly enable it in ldap.conf. If
sudoOrder is not present in an entry, a value of 0 is used. If no
entries contain sudoOrder attributes, the results are in whatever
order the LDAP server returns them, as in past versions of sudo.
Older versions of sudo will simply ignore the new attributes if
they are present.
Hope that clears things up.
