[Samba] Samba LDAP caching when LDAP server unavailable - possible?

I've been using Samba with OpenLDAP with great success on normal servers.
Recently however, it appeared to us that for remote locations it is more
economically viable to replace Samba servers with Samba running on
little routers like ASUS WL-500g with openwrt firmware/software.
It has a broadcom/mipsel CPU, and thanks to openwrt
(http://openwrt.org), it is possible to run lots of software on it.
Pretty nice for small offices - small, no fan, no hard disk etc. other
moving parts (you can connect a USB stick to it if you want to store
There is one glitch however - no OpenLDAP port.
So a Samba domain controller running on these tiny routers would have to
authenticate users users against an external OpenLDAP server (probably
in the company headquaters).
My experience shows that a company with several branches located
throughout the city/country/world have connectivity problems from time
to time (especiall when there is no IT staff in the branches).
With no local LDAP server this would mean users not able to work (as
they can't authenticate).
Is it possible to set up Samba to "cache" credentials retrieved from the
LDAP, and when LDAP is unavailable, to use these cached credentials?
