for the french-speaking readers of this mailing list here is a rather
comprehensive paper on the implementation and the architecture of 389
in heterogeneous environments (universities).
There is also a discussion of a real experience of cohabitation of 389
Server and Active Directory as well as comparison and argumentation of
the choice among AD/389/OpenLDap. It is a presentation made on
bi-annual JRES (les journées réseaux, "network days") conference.
