libnss-winbind should allow installation of the 32 bit libarary in trusty

[Jason Gunthorpe]

This is a regression. Prior versions of Ubuntu allowed the 32 bit and 64 bit libnss-winbind library to co-exist on the same system.

This is important as 32 bit binaries running on a 64 bit system can still access NSS services and must still be able to load the nss-winbind plugin.

The same comment applies to PAM as well, but I have no 32 bit apps using PAM so it isn't as interesting....

I've got the same problem.

Status changed to 'Confirmed' because the bug affects multiple users.

I've got the same problem. We are using several closed source tools (for FPGA building, code analysis, etc) which are 32-bit and e.g. call getpwuid(). A few segfault because of the returned NULL pointer return value caused by the missing libnss_winbind library.

I was able to install 64-bit winbind on Mint 18 but not 32-bit.
