[Pkg-samba-maint] Bug#881100: libnss-winbind is not multiarch safe

[Matthew Gabeler-Lee]

Package: libnss-winbind
Version: 2:4.5.12+dfsg-2
Severity: normal

Background: I use libnss-winbind, and a mulitiarch amd64/i386 system because
I need to run some third party i386 binaries.  At least one of those
binaries needs to be able to do nss lookups for some basic account information.

Trying to install libnss-winbind:i386 fails because:

1) It depends on the i386 version of the main winbind package.  This seems
   wrong-ish?  It just needs _some_ version of winbind installed so it can
   talk to it over the socket.

2) It depends on samba-libs, which fails multiarch because of at least
   #862338, though it's not immediately obvious to me _why_ it depends on
   samba-libs if the nss lib is just a thin shim to talk to other daemons? 
   If it's dlopening stuff from that, though, it'd make sense.
