<samba:parameter name="domain master" type="boolean" context="G" basic="1" advanced="1" developer="1" xmlns:samba="http://www.samba.org/samba/DTD/samba-doc"> <description> <para> Tell <citerefentry><refentrytitle>smbd</refentrytitle> <manvolnum>8</manvolnum></citerefentry> to enable WAN-wide browse list collation. Setting this option causes <command moreinfo="none">nmbd</command> to claim a special domain specific NetBIOS name that identifies it as a domain master browser for its given <smbconfoption name="workgroup"/>. Local master browsers in the same <smbconfoption name="workgroup"/> on broadcast-isolated subnets will give this <command moreinfo="none">nmbd</command> their local browse lists, and then ask <citerefentry><refentrytitle>smbd</refentrytitle> <manvolnum>8</manvolnum></citerefentry> for a complete copy of the browse list for the whole wide area network. Browser clients will then contact their local master browser, and will receive the domain-wide browse list, instead of just the list for their broadcast-isolated subnet. </para> <para> Note that Windows NT Primary Domain Controllers expect to be able to claim this <smbconfoption name="workgroup"/> specific special NetBIOS name that identifies them as domain master browsers for that <smbconfoption name="workgroup"/> by default (i.e. there is no way to prevent a Windows NT PDC from attempting to do this). This means that if this parameter is set and <command moreinfo="none">nmbd</command> claims the special name for a <smbconfoption name="workgroup"/> before a Windows NT PDC is able to do so then cross subnet browsing will behave strangely and may fail. </para> <para> If <smbconfoption name="domain logons">yes</smbconfoption>, then the default behavior is to enable the <smbconfoption name="domain master"/> parameter. If <smbconfoption name="domain logons"/> is not enabled (the default setting), then neither will <smbconfoption name="domain master"/> be enabled by default. </para> <para> When <smbconfoption name="domain logons">Yes</smbconfoption> the default setting for this parameter is Yes, with the result that Samba will be a PDC. If <smbconfoption name="domain master">No</smbconfoption>, Samba will function as a BDC. In general, this parameter should be set to 'No' only on a BDC. </para> </description> <value type="default">auto</value> </samba:parameter>
