It's just a cache.  Temporary high speed storage of lookups.  By
default, the data in the cache only lives for 300 seconds before winbind
queries the server (again) for current mappings.

If you're losing mappings or generating different mappings on a restart,
something else is wrong.  Not enough info here to make even an educated
guess.
