Cool LDAP class for AD

[countnikon]

I built this class for LDAP authentication and Schema Searches.  I thought you all might like it.  It also handle more than one OU which all the LDAP classes I've seen do not handle.  Here it is for what it's worth.

LDAP Class                                                                               
Class Created 7-5-06                                                                     
This class allows for LDAP searches and authentication against AD.                       
You can use a foreach loop in your code that calls this class to display all entries

Example LDAP Search.

$ldap->ldapConn();                                                                       
$bind=$ldap->ldapBind("ldapuser","ldappass");                                         
if($bind==false)                                                                         
  echo "Bind Failed<br>";
//This goes as follows
//ldapSearch('what you want to pull','self explanitory','your ou array','what you are searching against')
//you can search against anything in the schema.                                                               
$description = $ldap->ldapSearch("description","$usrname",$ouArray,"samaccountname");   
if($description)                                                                         
{                                                                                       
  foreach($description as $output)
