Subject: 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
-   method of using the routines.  We actually cache policy handles - tng
-   caches connections to pipes.
+   method of using the routines.
 
    The TNG design is quite good but I disagree with some aspects of the
