Tell smbd 8 to enable WAN-wide browse list collation. Setting this option causes nmbd to claim a special domain specific NetBIOS name that identifies it as a domain master browser for its given . Local master browsers in the same on broadcast-isolated subnets will give this nmbd their local browse lists, and then ask smbd 8 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.
Note that Windows NT Primary Domain Controllers expect to be able to claim this specific special NetBIOS name that identifies them as domain master browsers for that 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 nmbd claims the special name for a before a Windows NT PDC is able to do so then cross subnet browsing will behave strangely and may fail. If yes, then the default behavior is to enable the parameter. If is not enabled (the default setting), then neither will be enabled by default.
When Yes the default setting for this parameter is Yes, with the result that Samba will be a PDC. If No, Samba will function as a BDC. In general, this parameter should be set to 'No' only on a BDC.
