[Bug] ioFTPD PHP user_query bad password

[St0rm]

There seems to be a problem with the io_user_query() function:

$uid = io_user_id("ioFTPD");
$password = "ioFTPD";
$userfile = io_user_open($uid);
$usermask = io_user_mask_init(UINFO_PASSWORD);
$userarray = io_user_query($userfile, $usermask);
print($userarray[0] . "<br />" . io_sha1($password));

This code should print 2 passwords that are exactly the same, but for some reason it doesn't. The output looks like this:

6045ff757913ff59ff10ffff4f2746ff4d4d6b32
6045b1757913f659b210fceb4f2746d74d4d6b32

The second password is the correct one, which matches the password in the corresponding user file. The first password matches nothing (not even a password from the other userfiles). Am I missing something here or is it a bug in one of the functions?

Looks like a bug to me. Every time a hex is > 9F (I guess), it's FF in the wrong password...
