<h4 id="rzahycrtnewreplica">Create a new replica server</h4>
|
||
|
|
<p>If you have set up a replication topology (see <a href="rzahycreatems.htm#rzahycreatems">Create a master server (replicated subtree)</a>)
|
||
|
|
with a master (server1) and a replica (server2), you can change the role of
|
||
|
|
server2 to that of a forwarding server. To do this you need to create a new
|
||
|
|
replica (server3) under server2.</p>
|
||
|
|
<ol type="1">
|
||
|
|
<li>Connect Web Administration to the master (server1)</li>
|
||
|
|
<li>Expand the Replication management category in the navigation
|
||
|
|
area and click <span class="bold">Manage topology</span>.</li>
|
||
|
|
<li>Select the subtree that you want to replicate and click <span class="bold">Show topology</span>.</li>
|
||
|
|
<li>Click the arrow next to the <span class="bold">Replication
|
||
|
|
topology</span> selection to expand the list of supplier servers.</li>
|
||
|
|
<li>Click the arrow next to the <span class="bold">server1</span> selection to expand the list of servers.</li>
|
||
|
|
<li>Select server2 and click <span class="bold">Add replica</span>.</li>
|
||
|
|
<li>
|
||
|
|
<p>On the <span class="bold">Server</span> tab of the <span class="bold">Add replica</span> window:</p>
|
||
|
|
<ul>
|
||
|
|
<li>Enter the host name and port number for the replica (server3)
|
||
|
|
you are creating. The default port is 389 for non-SSL and 636 for SSL. These
|
||
|
|
are required fields.</li>
|
||
|
|
<li>Select whether to enable SSL communications.</li>
|
||
|
|
<li>Enter the replica name or leave this field blank to use the
|
||
|
|
host name.</li>
|
||
|
|
<li>Enter the replica ID. If the server on which you are creating
|
||
|
|
the replica is running, click <span class="bold">Get replica ID</span> to
|
||
|
|
automatically prefill this field. This is a required field, if the server
|
||
|
|
you are adding is going to be a peer or forwarding server. It is recommended
|
||
|
|
that all servers be at the same release.</li>
|
||
|
|
<li>Enter a description of the replica server.</li></ul>

in two places:

secure. Credentials placed in the replicated subtree are created beneath

<li>From the list of supplier capabilities, you can deselect any capabilities

that you do not want replicated to the consumer.
|

|
|
<p>If your network has a
|
||
|
|
mix of servers at different releases, capabilities are available on later
|
||
|
|
releases that are not available on earlier releases. Some capabilities, like
|
||
|
|
filter ACLs and password policy, make use of operational attributes that are
|
||
|
|
replicated with other changes. In most cases, if these functions are used,
|
||
|
|
you want all servers to support them. If all of the servers do not support
|
||
|
|
the capability, you do not want to use it. For example, you would not want
|
||
|
|
different ACLs in effect on each server. However, there might be cases where
|
||
|
|
you might want to use a capability on the servers that support it, and not
|
||
|
|
have changes related to the capability replicated to servers that do not support
|
||
|
|
the capability. In such cases, you can use the capabilities list to mark
|
||
|
|
certain capabilities to not be replicated.</p></li>

information on how to do that.</li>
