Re: altServer attribute for OpenLDAP

["Kurt D. Zeilenga" <Kurt@OpenLDAP.org>]

In OpenLDAP 2.1, you can configure altServer on a per-server
basis via the rootdse directive, see slapd.conf(5) for details.

There is really no good way to determine the proper settings
automagically as no one server knows what replicas might
exist nor, of these, which replicas are available to which
clients.  Hence, it's best left to the administrator to set.
