Hmm....

Just based on my past experiences with NIS (working on learning LDAP as we speak), one would normally have SOME local user data.

For example, a local sendmail user, a local root user, if you're running a MySQL daemon locally, you'd have a local mysql user.

I think? Someone could correct me if I'm wrong here, but I see little benefit from having the smmsp user being in ldap and not local to the machine. Feel free to prove me wrong on this though. :)

I'd still be interested in hearing about ldap caching, as it relates to me earlier question about laptop users and centralized auth.

We're in the midst of implementing a couple of FreeBSD servers, each

PADL's nss_ldap and pam_ldap modules, and while things work well, I'm
looking for ways to improve performance and reduce active queries against
LDAP.

There's no user information on the local system at all, so every operation
that requires UID/GID information had to do an LDAP lookup to get UID/GID
data.  So, for example, every piece of mail delivered means an LDAP lookup.
Ick.

Is there such a thing as nscd for FreeBSD, and if so, has anyone had
experience using it?  I found a lookupd utility that looks promising, but
I'm leery of implementing it in production as it seems like fairly untested
software.

Failing nscd or a similar thing, are there other ways I can cache this
infomration or otherwise improve performance?

Thanks.
