[Pkg-samba-maint] Bug#594088: samba-common: wins server not added to /etc/samba/dhcp.conf

[Maxim Nikulin]

Package: samba-common
Version: 2:3.4.8~dfsg-2
Severity: normal

/etc/samba/dhcp.conf file remains empty, although dhcp client receives
netbios-name-servers. If I add "wins server" to dhcp.conf by hand,
the file becomes empty on DHCP RELEASE event (ifdown eth0).
'ifup eth0' updates dhcp.conf modification time but it remains empty.

The DHCP client
ii  isc-dhcp-clien 4.1.1-P1-9     ISC DHCP client
sets emty new_netbios_name_servers environment variable on DHCP RELEASE.
This wipes out "wins server" record from dhcp.conf. It should be
intended behaviour of /etc/dhcp3/dhclient-enter-hooks.d/samba
script. On DHCP BOUND event the scripts have equal
new_netbios_name_servers == old_netbios_name_servers variables.
dhclient-enter-hooks.d/samba has a special check for this case
and do nothing for this network interface, so "wins server" is not added 
to /etc/samba/dhcp.conf.

I think, early "return"s from /etc/dhcp3/dhclient-enter-hooks.d/samba
should be removed.
