Apple Mac OS X Server (version 10.2.3 or later) - Manual (Page 107)

Directory Services 107
m With DHCP binding, a DHCP server automatically supplies the address and NetInfo tag of
the shared NetInfo domain. To use DHCP binding, the DHCP server must be configured
to supply a NetInfo parent’s address and tag. For instructions, see “Setting NetInfo
Options for a Subnet” on page 508 in Chapter 11, “DHCP Service.”
m With broadcast binding, the computer locates a shared NetInfo domain by sending out an
IP broadcast request. The computer hosting the shared domain responds with its address
and tag.
For broadcast binding, both computers must be on the same IP subnet or on a network
that is configured for IP broadcast forwarding.
The parent domain must have the NetInfo tag “network.”
The parent domain must have a machine record for each of its child domains. See “Adding
a Machine Record to a Parent NetInfo Domain” on page 107 for more information.
If you configure a computer to use multiple binding protocols and a parent is not located
with one protocol, another one is used. The protocols are used in this order: static, DHCP,
broadcast.
You can configure NetInfo binding by using the Directory Access application.
To bind a Mac OS X computer to a shared NetInfo domain:
1 In Directory Access, click the Services tab.
2 If the lock icon is locked, click it and type the name and password of a server administrator.
3 Select NetInfo in the list of services, then click Configure.
4 Select the binding protocols that you want the computer to use.
For broadcast binding, select “Attempt to connect using Broadcast protocol.”
For DHCP binding, select “Attempt to connect using DHCP protocol.”
For static binding, select “Attempt to connect to a specific NetInfo server.” Then enter the IP
address of the parent domain’s computer in the Server Address field and the parent domain’s
NetInfo tag in the Server Tag field.
5 Click OK, then click Apply.
6 Restart the computer.
Adding a Machine Record to a Parent NetInfo Domain
Mac OS X computers can bind their directory domains to a parent NetInfo domain by
using broadcast binding. The parent NetInfo domain must have a machine record for each
Mac OS X computer that can bind to it with broadcast binding. You can create a machine
record with the NetInfo Manager application.
