When using VMware as the connection plugin to connect to remote hosts you commonly set two facts for username and password:
ansible_vmware_tools_user: "mkamner"
ansible_vmare_tools_password: "Super Secret PW"
This will work just fine for windows and with many tasks on linux.
However, if you want to use become: true on linux it will fail with the strangest error messages.
For example: apt will fail, because it can’t acquire the lock file
The solution is rather simple, become does not honor the VMware facts set, instead it wants two different facts set:
ansible_user: "mkamner"
ansible_password: "Super Secret PW"
