In general it's quite simple
public function getusercn($accountname)
{
$filter_person = "(&(sAMAccountName={$accountname}))";
$sr_person = ldap_search($this->ds_ad,$this->base_user_dn,$filter_person);
$sr = ldap_get_entries($this->ds_ad, $sr_person);
$attr = $sr[0]["givenName"][0];
return $attr;
}
$this->ds_ad - it's $ds in your code
$this->base_user_dn - is base OU from which you want to search (like LDAP_TOP in your case)
sAMAccountName - is "user id" attribute in your case uid
givenName - is attribute what you are looking for
All of attributes are already in $sr variable, so you can use var_dump to inspect all content.
