I'll second the desire for python bindings for samba functionality that, while
doable by running CLI tools and scraping their output, are more elegant and
efficient when using an API. Specifically, I'd (probably) also be able to make
use of these CTDB related APIs in my code.

May I humbly suggest that re-implementing the ctdb CLI not be a strict
requirement to adding useful Python APIs. There's been a number of cases with
regards to Samba where a small-enough task suddenly gets bigger in scope and
then either takes a very long time to get merged (if ever).
