> same for token... as for uuid, i think that is safe to cache the token on the cls.os_user so that we don't have to re-create it for each test.... 

I've implemented SID caching in this ticket as it was added here.

I've left caching of the token for the `TestUser(s)` refactoring ticket. I would like to discuss how to do it: I don't like that the token is obtained via manufacture at the moment, instead of the OS administration API.
