Comment 4 for bug 1629107

Yakkety has the same version still, so no wonder it applies there as well:
[21225.454247] rpc.yppasswdd[23877]: segfault at 0 ip 00007fb4ab16f5ca sp 00007ffe262e6588 error 4 in libc-2.24.so[7fb4ab0cf000+1bd000]

Debian needs to add a user before ypinit as its LXD images have no non-root default user
 $ useradd test
But other than that this applies to Debian as well leading to:
rpc.yppasswdd[26200]: segfault at 0 ip 00007fef59ccb34a sp 00007ffc225f75a8 error 4 in libc-2.24.so[7fef59c3c000+195000]

Since Debian-sid just recently updated to upstream nis I have to assume that this is an upstream issue or of the way Debian & Ubuntu are integrating it.
