The example didn't work for me with the following error (on freeipa 4.9.8):

TASK [display default login shell] **************************************************************************************************
fatal: [freeipa1.example.org]: FAILED! => {"msg": "
The task includes an option with an undefined variable. The error was: 'dict object' has no attribute 'defaultlogin'

Using the correct variable defaultshell works for me.
