I don't get why, /tmp is not the only directory in a filesystem.
As I said in Fedora/RHEL we simply moved the pipe to /var/run/winbindd
what's the problem with that ?

DBUS is a unix pipe like we have in winbindd just with a different more
generic protocol. You are welcome to use it if you like but it is not
necessary.
You may mean the system message bus (that uses libdbus as the
transport), but that's not meant to carry a lot of data, so it is
inadvisable to sue it for the winbindd protocol.

Simo.
