Caching user, group and domain sam handles was a stupid idea.
Now we just keep a record of the open pipes. (This used to be commit 77c287e9460eed7bde7004c7e6c8cb0099c6ba6f)

like that but at the moment it's simply staying as part of winbind. I
think the TNG architecture of forcing every user of the rpc layer to use
the connection caching system is a bad idea. It should be an optional
