We don't expect to be able to mix CTDB across Samba 4.x minor versions.

We do expect to be able to mix CTDB across Samba 4.x.y release versions.

In particular, 4.4 + 4.5 will fail because we dropped database
priorities and associated controls.

This policy needs to be documented on the wiki somewhere.  I'll get to
it soon... along with a major reorganisation of the CTDB documentation
and wiki material...

peace & happiness,
