This is more of a samba question....

I'll be setting up zimbra + samba using this tutorial, an all in one server: Zimbra Integration With Samba - Ubuntu Based (Similar To AD And Exchange) | HowtoForge - Linux Howtos and Tutorials

My question is if I have more than one samba file server in addition to the zimbra server, how do I point these other samba servers to use the samba/LDAP on the zimbra server? Can someone point me to a link, or shed some light, on how to setup samba on these other servers?
