27 We need to manage connections to domain controllers without having to
28 mess up the main winbindd code with other issues. The aim of the
29 connection manager is to:
31 - make connections to domain controllers and cache them
32 - re-establish connections when networks or servers go down
33 - centralise the policy on connection timeouts, domain controller
35 - manage re-entrancy for when winbindd becomes able to handle
36 multiple outstanding rpc requests
38 Why not have connection management as part of the rpc layer like tng?
39 Good question. This code may morph into libsmb/rpc_cache.c or something
40 like that but at the moment it's simply staying as part of winbind. I
41 think the TNG architecture of forcing every user of the rpc layer to use
42 the connection caching system is a bad idea. It should be an optional
43 method of using the routines.
45 The TNG design is quite good but I disagree with some aspects of the
53 - I'm pretty annoyed by all the make_nmb_name() stuff. It should be
54 moved down into another function.
56 - Take care when destroying cli_structs as they can be shared between
