It appears that Pywikibot does not support auto-creation of local accounts under SUL. Auto-creation happens on someone's first visit to a SUL-connected wiki when they have a global account. It's apparently supported by MediaWiki API, too.
Could login.py support auto-creation?
Currently, when I try to log in to a new SUL-connected wiki, it will result in NoUsername:
