The "test case" is a one byte file containing a zero byte. But here it
is :-)

samba 4.4rcx WINS nsswitch module
WINS nsswitch module
--------------------
The WINS nsswitch module has been rewritten to address memory issues and to
simplify the code. The module now uses libwbclient to do WINS queries. This
means that winbind needs to be running in order to resolve WINS names using
the nss_wins module. This does not affect smbd.
