* Add support for `sudo su -` using password auth
Allow users to run Ansible tasks through `sudo su -` using password auth
- Feature Pull Request
sudosu
So I have been using this at various customers for bootstrapping Ansible mostly.
Often you have an existing setup where there is a user that has root-access enabled through sudo, but only to run `su` to log using the user's password.
In these specific cases the root password is unique to the system and therefore not an easy way to automate bootstrapping.
Having a `sudo su -` become option **with password prompt** is not possible with the existing become methods (neither sudo nor su can be used) by abusing `become_exe` or `become_flags`.
This fixes ansible/ansible#12686
