d.
If you have enabled the password expiration policy or intend to do so in
the future, disable it to prevent replication from failing due to expiration
of passwords.
To disable the password expiration policy on the
userPassword
attribute,
add the
passwordExpirationTime
attribute with a value of
20380119031407Z
, which means that the password will never expire.
3.
On Server A and Server B, specify the replication settings for the
multi-mastered read-write replica.
a.
In the Directory Server Console, select the Configuration tab.
b.
Expand the Replication node, and select the database to replicate.
The Replica Settings tab is displayed on the right pane.
c.
Check the Enable Replica checkbox.
d.
In the Replica Role section, select the Multiple Master radio button.
e.
In the Common Settings section, specify a Replica ID.
The replica ID must be an integer between
1
and
254
, both inclusive, and
must be unique for a given suffix. Make sure you specify an ID that is
different from the IDs used for read-write replicas on this server and on
other servers.
f.
In the Common Settings section, specify a purge delay in the “Purge
delay” field.
This option indicates how often the state information stored in the
replicated entries is purged.
g.
In the Update Settings section, specify the supplier bind DN or entry DN
that the supplier will use to bind to the replica.
This supplier bind DN should correspond to the entry created in Step 2.
The supplier bind DN corresponds to a privileged user because it is not
subject to access control.
h.
Specify the supplier server to which you want to refer updates (the other
supplier in the multi-master set).
Only specify the URL for the supplier server if you want clients to bind
using SSL. In such a case, you must specify a URL beginning with
ldaps://
.
