Of course this is not idempotent. Mmm, security is difficult.

Hello,



Glad to hear that you got it to work.

Before you put this into production, please make sure you don't re-use the same 
salt value. Try to randomize it. Something like 
seeded_rand_string(16,strftime("%s%L")) may work.

I figured it out. Thanks for the help. It's because I wasn't doing I

 password           => pw_hash('password', 'SHA-512', 'mysalt'),

 I was doing

Sensitive(pw_hash('$password', 'SHA-512', 'oursalt')),

And because I used single quotes, it wasn't actually getting the parameter / 
variable, but the literal $password. Remove the quotes entirely because it's 
just a variable, and it works!

And this is why you can't always just copy -> paste -> edit your stuff in!.

Hello,



I'm still puzzled by why this is not working on your system. The following 
works for me on a Centos7 machine:



user { 'testuser':
  ensure             => 'present',
  password           => pw_hash('password', 'SHA-512', 'mysalt'),
}

So, I set the password manually with passwd and got an entirely different hash 
than when I use the pw_hash function. The salt is obviously different as well, 
but the rest of /etc/shadow entry is the same. ssh user@localhost works with 
the password when I set manually with passwd, and does not work with pw_hash - 
not surprisingly.
 I tried lowercase sha-512, and got the same hash as with uppercase SHA-512. 
Both methods (working manual passwd, and non working pw_hash) start with $6$ 
which implies a sha-512 hash from the docs, so I think pw_hash is just broken 
for EL7. Which means the user resource is broken.

I guess temporarily, I'll just set the hash as a string and generate it with 
passwd, and see if that works - but it's obviously not ideal.
