Describe the bug

It should be working fine, and filter out non-local users

Actual behavior

@mvisonneau What kind of "non-local" users do you have in your setup?

[mvisonneau]

I have ldap users, bound on an active directory

Right now I have neither Puppet 6 nor LDAP in my own test environment ... I'll try to set this up, but it will take some time ...

I have now setup a similar system (Ubuntu 18.04 with Puppet 6.2.0) and connected it to our AD. For this I was following this guide. I can now work with an AD user on the test system, also a home directory has been created. But there's no entry in /etc/passwd for this AD user.

And if I run puppet agent -t, I get no error (os_hardening and many other modules are used in my ruleset). My puppet server ist still v5, but this shouldn't matter (will try to upgrade the next days).

So what's different in our setup?

@mvisonneau My Puppet Server is now also on v6, and still I cannot reproduce this. Could you please paste in your /etc/passwd file?

@mvisonneau Any news here?
