AFAIK Samba does not cache them. However, group memberships 
are processed by the OS at user login, not every time an 
access is attempted. If the smbd process servicing a 
workstation doesn't die, they won't be recalculated. SMB is 
very odd about when a connection is actually closed.

At least you know to some extent what's going on now, even 
though I don't have a solution for you.
