[ggiesen]

While running a state.apply to join a Salt 3005 OneDir minion to FreeIPA, I receive the following error:

minion:

Per the note on this page:

Warning

When using a mode that includes a leading zero you must wrap the value in single quotes. If the value is not wrapped in quotes it will be read by YAML as an integer and evaluated as an octal.
