Using this feature, you don't have to use virtual host protection: protection is embedded in Lemonldap::NG::Handler::CGI.
|
|
</p>
|
|
|
|
<p>
|
|
Lemonldap::NG::Handler::CGI adds some functions to <a href="http://search.cpan.org/perldoc?CGI" class="urlextern" title="http://search.cpan.org/perldoc?CGI" rel="nofollow">CGI</a>:
|
|
</p>
|
|
<ul>
|
|
<li class="level1"><div class="li"> authenticate: check if user is authenticated; if not, redirect it to the portal</div>
|
|
</li>
|
|
<li class="level1"><div class="li"> authorize: check if user is authorizated to access to this <abbr title="Uniform Resource Locator">URL</abbr></div>
|
|
</li>
|
|
</ul>
|
|
|
|
<p>
|
|
Example:
|
|
</p>
|
|
<ul>
|
|
<li class="level1"><div class="li"> Code to replace:</div>
|
|
</li>
|
|
</ul>
|
|
<pre class="code perl"><span class="kw1">my</span> <span class="re0">$cgi</span> <span class="sy0">=</span> <span class="kw2">new</span> CGI<span class="sy0">;</span>
|
|
<span class="sy0">...</span></pre>
|
|
<ul>
|
|
<li class="level1"><div class="li"> New code:</div>
|
|
</li>
|
|
</ul>
|
|
<pre class="code perl"><span class="kw1">my</span> <span class="re0">$cgi</span> <span class="sy0">=</span> Lemonldap<span class="sy0">::</span><span class="me2">NG</span><span class="sy0">::</span><span class="me2">Handler</span><span class="sy0">::</span><span class="me2">CGI</span><span class="sy0">-></span><span class="kw2">new</span> <span class="br0">(</span><span class="br0">{</span><span class="br0">}</span><span class="br0">)</span><span class="sy0">;</span>

Then you can access to user datas
|
|
</p>
|
|
<pre class="code perl"><span class="co1"># Get attributes (or macros)</span>

<span class="kw1">my</span> <span class="re0">$cn</span> <span class="sy0">=</span> <span class="re0">$cgi</span><span class="sy0">-></span><span class="me1">user</span><span class="sy0">-></span><span class="br0">{</span>cn<span class="br0">}</span>
|
|
|
|
<span class="co1"># Test if user is member of a Lemonldap::NG group (or LDAP mapped group)</span>

<span class="kw1">if</span><span class="br0">(</span> <span class="re0">$cgi</span><span class="sy0">-></span><span class="me1">group</span><span class="br0">(</span><span class="st_h">'admin'</span><span class="br0">)</span> <span class="br0">)</span> <span class="br0">{</span>
|
|
<span class="co1"># special html code for admins</span>

<span class="br0">}</span>
|
|
<span class="kw1">else</span> <span class="br0">{</span>
|
|
<span class="co1"># another HTML code</span>
|
|
<span class="br0">}</span></pre>
|
|
|
|
<p>
|
|
You can test any <abbr title="Uniform Resource Locator">URL</abbr> to see if it's protected using testUri(). It returns:
|
|
</p>
|
|
<ul>
|
|
<li class="level1"><div class="li"> 1 if user is authorizated to access to it</div>
