This is an abstracted library in Go that wraps around libnss, allowing you to write new nss modules purely in Go.
Right now we only have binding for passwd, group, and shadow. This may change in the future to also implement other NSS features. These are just the most obvious first targets.
First you should go get the package:
go get github.com/protosam/go-libnss
Take a gander at the example directory. It includes information on how to compile the example and you can use the implementation as a boiler plate for your own project.
