nsncd is a nscd-compatible daemon that proxies lookups, without caching.
nsncd can be used in situations where you want to make an application use nss
plugins available to a different libc than the one the application will load.
Since most (all?) libc implementations will try to use /var/run/nscd/socket if
it exists, you can make all lookups on a machine attempt to use the libc that
nsncd is running with (and any nss plugins available to it), regardless of the
libc used by a particular application.
It is also a fairly minimal and clean implementation of (a part of) the nscd
protocol, which is otherwise only really documented in implementations of libc,
and mailing lists.
Just run the nsncd binary and it will listen at /var/run/nscd/socket.
There's a simple systemd unit file, too.
If you're on a Debian-based system, you can use the provided Debian package to
install nsncd to run under systemd. See debian/README.source for how to
build it - we use a few Rust crates that aren't packaged for stable Debian
releases.
