Hi Rowland,

You say that winbind can do anything that sssd can, yet I've not been 
able to find winbind instructions similar to these for sssd: 

Do you know of such instructions? More particularly, do you know how 
with winbind we can lock sudoers down to specific OUs? We need to do a 
lot more than basic authentication and simple file sharing. From both 
this thread and previous ones I suspect our environment is more complex 
that what you're familiar with.
