Next the automatic search policy looks at the binding of shared NetInfo domains. The
computer’s local domain may be bound to a shared NetInfo domain, which may in turn be
bound to another shared NetInfo domain, and so on. The NetInfo binding, if any, constitutes
the second part of the automatic search policy. See “Configuring NetInfo Binding” on
page 111 for additional information.
The third and final part of a computer’s automatic search policy consists of shared LDAPv3
domains. They are included only if the computer uses a DHCP service that’s configured to
supply the addresses of one or more LDAPv3 servers. The DHCP service of Mac OS X Server
can supply LDAPv3 servers. See “Setting the LDAP Server for DHCP Clients” on page 479 in
Chapter 11, “DHCP Service.”
A computer’s automatic search policy may change if the computer is moved to a part of the
network served by a different DHCP service. When the user logs in at the new location, the
computer connects to the new DHCP service. The new DHCP service may change the
NetInfo binding and may supply a different list of LDAPv3 servers than the DHCP service at
the former location.
Custom Search Policies
If you don’t want a Mac OS X version 10.2 computer—server or client—to use the automatic
search policy supplied by DHCP, you can define a custom search policy for the computer.
In this scenario, a custom search policy specifies that LDAP Server 1 be consulted when a
user record or other administrative data cannot be found in the directory domains of the
automatic search policy. The custom search policy also specifies that if the user information
or other administrative data is not found on the LDAP server, a shared Open Directory
domain named “Campus” is searched.
Students domain
Graduates domain
Local domain
LDAP Server 1
Campus domain
