Chapter 5 Setting Up Open Directory Services 91
After setting up a BDC, you might want to change access restrictions, logging detail
level, code page, domain browsing, or WINS registration. Then if Windows services
aren’t running, you can start them. For more information, see Network Services
Administration.
Setting Up Open Directory Failover
If an Open Directory master or its replicas become unavailable, client computers that
use v10.3–v10.6 of Mac OS X or Mac OS X Server nd an available replica and connect
to it.
If a failed Open Directory master or replica had client computers with Mac OS X or
Mac OS X Server v10.2 or earlier, the v10.2 computers and servers do not automatically
fail over to another replica.
Replicas only permit clients to read directory information. Directory information about
a replica can’t be modied with administration tools such as Workgroup Manager.
Users whose password type is Open Directory can change their passwords on
computers that are connected to Open Directory replicas. The replicas synchronize
password changes with the master. If the master is unavailable for a while, the replicas
synchronize password changes with the master when it becomes available again.
If the Open Directory master fails permanently and you have a current archive of its
data, you can restore the data to a new master. Alternatively, you can promote a replica
to be the master. For more information, see “Restoring an Open Directory Master” on
page 197 and “Promoting an Open Directory Replica” on page 192.
If you replace a failed master by promoting a replica to be the master, you can
manually recongure each computer and server to connect to this new master or
one of its replicas. You do this by using Account preferences (or Directory Utility for
advanced connections) on each computer or server to create an LDAPv3 conguration
that species how the computer accesses the new master or an available replica.
For more information, see “Using Advanced LDAP Service Settings” on page 133.
