[Douglas Gameiro Diniz]

Brief Description
-----------------
When we try to run an Ansible command that needs to become root, it fails when trying do to the privilege escalation.

Severity

Minor

Steps to Reproduce

Try to run the following command on any controller:

ansible localhost -K -b -m shell -a "whoami" -c local

Expected Behavior

It should print "root".

Actual Behavior
----------------
The command hangs forever.

Reproducibility
---------------
It happens 100% of the time on all the systems I tested.

System Configuration
--------------------
Simplex and Standard 2+2, but probably happens in any configuration.

Branch/Pull Time/Commit

Last Pass
---------
This error is occurring for some time and there is no information about the last pass.

Timestamp/Logs

Workaround
----------
Run a command as root before running the ansible command. For example a "sudo ls". This way it will run as sudo while the sudo session remains active for some minutes.
