9 Tell <citerefentry><refentrytitle>smbd</refentrytitle> <manvolnum>8</manvolnum></citerefentry> to enable
10 WAN-wide browse list collation. Setting this option causes <command moreinfo="none">nmbd</command> to claim a
11 special domain specific NetBIOS name that identifies it as a domain master browser for its given
12 <smbconfoption name="workgroup"/>. Local master browsers in the same <smbconfoption name="workgroup"/> on
13 broadcast-isolated subnets will give this <command moreinfo="none">nmbd</command> their local browse lists,
14 and then ask <citerefentry><refentrytitle>smbd</refentrytitle> <manvolnum>8</manvolnum></citerefentry> for a
15 complete copy of the browse list for the whole wide area network. Browser clients will then contact their
16 local master browser, and will receive the domain-wide browse list, instead of just the list for their
17 broadcast-isolated subnet.
21 Note that Windows NT Primary Domain Controllers expect to be able to claim this <smbconfoption
22 name="workgroup"/> specific special NetBIOS name that identifies them as domain master browsers for that
23 <smbconfoption name="workgroup"/> by default (i.e. there is no way to prevent a Windows NT PDC from attempting
24 to do this). This means that if this parameter is set and <command moreinfo="none">nmbd</command> claims the
25 special name for a <smbconfoption name="workgroup"/> before a Windows NT PDC is able to do so then cross
26 subnet browsing will behave strangely and may fail.
30 If <smbconfoption name="domain logons">yes</smbconfoption>, then the default behavior is to enable the
31 <smbconfoption name="domain master"/> parameter. If <smbconfoption name="domain logons"/> is not enabled (the
32 default setting), then neither will <smbconfoption name="domain master"/> be enabled by default.
36 When <smbconfoption name="domain logons">Yes</smbconfoption> the default setting for this parameter is
37 Yes, with the result that Samba will be a PDC. If <smbconfoption name="domain master">No</smbconfoption>,
38 Samba will function as a BDC. In general, this parameter should be set to 'No' only on a BDC.
