netusers.managed failing, is this something outside of my control?

[nzurku]

Hello.

I'm trying to run the netusers.managed via a state. I'm actualy using the example SLS as referenced here: https://docs.saltstack.com/en/master/ref/states/all/salt.states.netusers.html

[root@salt-junos]# salt 'spsw-1*' state.apply pit1/baseline test=True
spsw-101.pit1:
----------
          ID: netusers_example
    Function: netusers.managed

I get healthy replies of modules such as netusers.config, and I can even create/delete users via the proper modules. I just can't use this managed module.
