Improve documentation of forcelocal and libuser on user resource documentation page

Puppet Version: 2016.4.x
Puppet Server Version: 2016.4.6
OS Name/Version: CentOS

I am working in an environment where users / groups are managed remotely via Samba. I'm trying to use the existing user documentation to manage some users locally but running into issues in understanding the documentation. The libuser "feature" seems relevant to what I want to accomplish but the documentation on this is extremely sparse on this page: https://puppet.com/docs/puppet/5.3/types/user.html#user-provider-features

Desired Behavior:

Improve existing documentation re: "libuser" and any associated requirements / dependencies. A few additional sentences explaining how the library can be used, any limitations, and on which particular Operating Systems it's supported would be extremely useful.

My understanding is that the current documentation is generated from source code and the associated in-line documentation will need to be updated in order to improve the documentation on the above page.
