We need to manage connections to domain controllers without having to
mess up the main winbindd code with other issues. The aim of the
connection manager is to:
-
+
- make connections to domain controllers and cache them
- re-establish connections when networks or servers go down
- centralise the policy on connection timeouts, domain controller
selection etc
- manage re-entrancy for when winbindd becomes able to handle
multiple outstanding rpc requests
-
+
Why not have connection management as part of the rpc layer like tng?
Good question. This code may morph into libsmb/rpc_cache.c or something
like that but at the moment it's simply staying as part of winbind. I
