Pb to change "accountexpires" attribute in Active Directory

Hi all, I'm currently setting up a php site to control my Active Direcory, and I'm struggling with the "Accountexpire" field. After extending the expiration date, I can't set it back in AD, because it is in scientific format (1.2774158851E+017). And I can't find how to transform this into an integer before making the AD request ! I've tried inval, double, sprintf, ... without success ! I event tried to use a string: $ADtime = ($PHPtime + 11644524000)."0000000", with no luck... I'm suspecting something inside the ldap_mod_replace function, but can't be sure Here's what my code looks like: $PHPtime = time(); $newExpiration = $PHPtime + (7 * 24 * 60 * 60); //add 1 week (7 days * 24 hours * 60 minutes * 60 seconds) $ADtime = ($PHPtime + 11644524000) * 10000000 ; $userdata["accountexpires"] = $ADtime; $result = ldap_mod_replace($ad, $myaccount->dn, $userdata); Any idea how to fix this ? thanks a lot, --------------------------------- Appel audio GRATUIT partout dans le monde avec le nouveau Yahoo!
