LDAP search from an Express Rule

Question

Hi,
I need to do a simple search in a LDAP directory from inside a Rule. I�m trying to do this from Express code but i�m not able and dont find any info about it in the forum.
I�m trying to do it with a code like:
<block>
<setvar name='context'>
<new class='javax.naming.ldap.InitialLdapContext'/>
</setvar>
<invoke name='search'>
<ref>context</ref>
<s>c=es</s>
<s>(cn=*)</s>
<s>null</s>
</invoke>
</block>
I dont know if i have to use javax.naming.ldap.InitialLdapContext or maybe the com.sun.jndi.ldap that comes with idM.
Any clue? Any sample code to do it?
Regards,

Here is a simple example of calling a custom Java Class to retrieve a users phone number from LDAP. Hope someone can return the favor by answering some of my posts.
              <invoke class="JNDIutility" name="getUsersPhoneNumber">
              <ref>:variables.employeeID</ref>
              <s>ou=NonEmployees,ou=People,dc=xxx,dc=xxx</s>
              </invoke>Here is the simple Java class:
