This is possible in principle using nslcd - and it should be with 
winbind as well. When libnss cannot contact ldap, it can fall back to 
local files. An option which I considered for notebooks, but I dropped 
it since it is confusing:

* it would also fall back to local shadow of course,
* you'd have to somehow sync group memberships to local files,
* perhaps the very users as well,
* and still lack any SSO benefits. (you're offline to begin with :) )

So it should be considered thoroughly why this is required and whether 
there are other ways to achive those goals.

  - lars.
