multi-site setup

[zippydan]

I want to setup a multi-site system so that users can move between sites, but authenticate to a local server and not a remote one.  This means LDAP will need to sync between the different sites.

Say I have "zenserv1" at "site1" with "site1user" and "zenserv2" at "site2" with "site2user".  For organizational purposes, should I be using the same domain like "company.lan" for both servers?  Or is it possible/recommended to use a domain of "site1.company.lan" on "zenserv1" and "site2.company.lan" on "zenserv2"?

As I understand it, local registration with synchronized servers is possible, but all email storage/authentication must be on one server only?

I do share this understanding too.
