What's the use for that? *ALL* your machines? How many do you have? I'm not sure
the slurpd would appreciate to replicate an average write flow to 50 servers!

Hmmm... the contrary would be odd :-)

In fact, with a slapd per server, it could not be more decentralized :)

Of course If you have 1 slapd / machine, I guess the name service caching daemon
isn't really useful. However I'd like to have more informations about that?
How "high" is your "traffic environment" ? I'm currently testing an LDAP-based
architecture for NIS replacement with OpenLDAP and the libnss-ldap/nscd on
client systems. It seems to work fine. Could you describe the troubles you got
more precisely?

A server (running as an LDAP client) has mysteriously frozen (answer to ping,
socket opening, but 0 traffic, no way to login on the console even though the
keyboard worked fine) this morning. I'm wondering if this could be due to the
nscd or the libnss-ldap [probably not]. Anyway what kind of hang up did you
get?
