small issue - solved - empty fields can cause error while updating

modifying a password of a new user I got

warning: ldap_mod_del(): Modify: Invalid syntax in /var/www/squadrainformatica.com/sites/all/modules/ldap_integration/ldap_integration/LDAPInterface.php on line 218.

I fixed it adding "if(!empty($old_value))" in LDAPInterface.phpc in front of "ldap_mod_del($this->connection, $dn, array($key => $old_value));"

so it's

if(!empty($old_value)) 	ldap_mod_del($this->connection, $dn, array($key => $old_value));
