[Evolution] sharing address books, probably with LDAP

[michael <cs networkingnewsletter org uk>]

I'm a newbie where LDAP is concerned but I see Evolution allows a user
to share address books via LDAP. (It's having the same address book for
diff machines running Evo that is the functionality I require - LDAP
just seems to be one/the Evo way) However, having installed slapd I
cannot work out how to configure things such that Evo creates/uses a
LDAP address book. Does anybody have a step-by-step guide? Cheers,
Michael
