Comment 17 for bug 1611816

For the record, I also tried yakkety on i386:

 *** 2:6.5-2ubuntu2 500
        500 http://br.archive.ubuntu.com/ubuntu yakkety-proposed/main i386 Packages

root@22-96:~# ll /lib/i386-linux-gnu/security/pam_cifscreds.so
-rw-r--r-- 1 root root 13568 Feb 28 21:58 /lib/i386-linux-gnu/security/pam_cifscreds.so

I performed the same test as for amd64 and it also worked.
