One of the tests in simp-core ./spec/acceptance/suites/default/10_rsyslog_integration_spec.rb +341 has to set the password for a local user.
It gets a token authentication error. I tried logging in a resetting it and still get a fail. I tried creating a new local user and setting it and that failed. I had no problem on my generic el8 system.
Possibly a problem with PAM?
