<p class="paragraph"></p><strong class="strong">Remark</strong>: we advice
to create a specific user/password in MySQL for LemonLDAP::NG, with rights
on ist database.
<h4 class="heading-1-1-1"><span id="HDatabasecreation">Database
creation</span></h4><br />
<br />
For example, create the database "lemonldapng" :<br />
<br />
<div class="code">
<pre>
# mysqladmin create lemonldapng
</pre>
</div>
<h4 class="heading-1-1-1"><span id="HSessiontable">Session
table</span></h4><br />
<br />
If you want to use Apache::Session::MySQL, you can create the database
like this:<br />
<br />
<div class="code">
<pre>
CREATE TABLE sessions (
id <span class="java-object">char</span>(32),
a_session blob
);
</pre>
</div>
<h3 class="heading-1-1"><span id=
"HLemonLDAP3A3ANGconfiguration">LemonLDAP::NG configuration</span></h3>
<p class="paragraph"></p>Go to the Manager and go in <strong class=
"strong">General Parameters &gt; Session Storage</strong>. Then change
<strong class="strong">Apache::Session module</strong> to
"Apache::Session::MySQL" and in <strong class="strong">Apache::Session
parameters</strong> configure the following options:
<ul class="star">
<li>DataSource (for example:
DBI:mysql:database=lemonldapng;host=127.0.0.1)</li>
<li>UserName</li>
<li>Password</li>
<li>TableName</li>
<li>LockDataSource</li>
<li>LockUserName</li>
<li>LockPassword</li>
</ul>You can also set the session module in perl scripts:
<div class="code">
<pre>
globalStorage =&gt; <span class="java-quote">"Apache::Session::MySQL"</span>,
globalStorageOptions =&gt; {
DataSource =&gt; <span class=
"java-quote">"dbi:mysql:database=lemonldapng;host=127.0.0.1"</span>,
UserName =&gt; <span class="java-quote">"db_user"</span>,
Password =&gt; <span class="java-quote">"db_password"</span>,
TableName =&gt; <span class="java-quote">"sessions"</span>,
LockDataSource =&gt; <span class=
"java-quote">"dbi:mysql:database=lemonldapng;host=127.0.0.1"</span>,
LockUserName =&gt; <span class="java-quote">"db_user"</span>,
LockPassword =&gt; <span class="java-quote">"db_password"</span>,
},
</pre>
