Not really a question for a fedora user list, but this is the only list I enjoy... First, can I use a single LDAP server to maintain two different address books (internal contacts / external contacts) and use it as an authentication system for two (or more) Linux machines? I'm trying to learn how to setup LDAP and I see all these tutorials for these tasks separately, but nothing that really says I can do it all at once with one server. Second, if the computer running the LDAP server fails in some manner is the database easily copied/mirrored to another server that can take over? Is it as easy as copy the config and data directory to the second machine and turn on the server? Or does LDAP have a built in structure for maintaining information among a primary/backup server?
