DHCP Binding
When you configure a Mac OS X computer to locate its parent using DHCP binding, the
parent’s IP address and NetInfo tag are provided by a DHCP server rather than using
information you enter using Directory Setup. To use DHCP binding, you must first
configure a DHCP server to provide this information.
Use this procedure to configure a Mac OS X computer to use DHCP binding:
1
Configure a DHCP server to provide the IP address and NetInfo tag of the parent domain. If
the DHCP server is hosted by a Mac OS X Server, use these steps.
a On the Mac OS X Server hosting the DHCP server, open Server Admin and log in as a
server administrator.
b Click the Network tab, click DHCP/NetBoot, and choose Configure DHCP.
c Select a subnet, then click Edit.
d Click the NetInfo tab.
e In the NetInfo Tag field, enter the NetInfo tag of the parent domain you are setting up
binding for.
f In the NetInfo Parents field, enter the IP address of the computer on which the parent
domain resides.
g Click Save.
2 On the Mac OS X computer for which you want to configure binding, open Directory Setup.
Click the lock icon and log in as the local administrator.
3 Select NetInfo and click Configure.
4 Choose “Attempt to connect using DHCP protocol.”
5 Click OK.
6 Restart the computer.
Broadcast Binding
This technique is the default if multiple binding options are not configured. The two
computers that need to bind must be on the same subnet or on a LAN configured for IP
broadcast forwarding. Also, the parent domain must have the NetInfo tag “network.”
Follow these steps to configure a Mac OS X computer to bind to a parent domain using
broadcast binding:
1 Add a machine record for the Mac OS X computer to the parent you want it to bind to:
a Open NetInfo Manager on the computer where the parent domain resides, then open
the domain.
b Click the lock icon and log in using the user name and password specified when the
domain was created.
