Hello, I am trying to use Invoke-VMScript to run a specific command on Linux guest machines.
The command errors with the following output:

In the linux host I’m currently trying I see the following in /var/log/audit/audit.log
type=USER_AUTH msg=audit(1603969482.812:4373542): pid=9477 uid=0 auid=4294967295 ses=4294967295 msg=’op=PAM:authentication grantors=? acct=”sa_vmware” exe=”/usr/bin/vmtoolsd” hostname=? addr=? terminal=? res=failed’
/var/log/vmware-vmsvc.log shows the following during the login:

/etc/pam.d/vmtoolsd Is the following:
auth required pam_shells.so
auth substack password-auth
auth include postlogin
account required pam_nologin.so
account include password-auth
with journalctl -xe I see
Oct 29 12:26:59 <REDACTED HOSTNAME> VGAuth[9477]: vmtoolsd: Username and password mismatch for ‘sa_vmware’.
I am completely sure the password entered in the command is the same as the user password.
