Failure in Ansible setup - missing python-ldap

[mudash]

Following error occurred during cluster setup

An exception occurred during task execution. To see the full traceback, use -vvv. The error was: ModuleNotFoundError: No module named 'ldap'
fatal: [mgmt.smiling-man.citc.local]: FAILED! => changed=false
  msg: Failed to import the required Python library (python-ldap) on mgmt.smiling-man.citc.local's Python /usr/bin/python3. Please read the module documentation and install it in the appropriate location. If the required library is installed, but Ansible is using the wrong Python interpreter, please consult the documentation on ansible_python_interpreter

Manually resolved by installing python3-ldap and re-running the ansible setup.
