could you set up a small instance of an ldap server along with samba on this small box and have it act like a bdc? you could set up openldap to do syncrepl and have a full copy of your samba domain stuff that's in ldap. if the connection goes down, the ldap stuff is there and if you have it set up like a bdc, you can still login, etc.

just a thought, i'm fairly new at all this stuff.

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 files/profiles).

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?
