LDAP PHP and logonHours

[Steve Board]

Can anyone help please.

I am trying to make use of the loginHours that are part of active
directory. The problem is I am trying to access this field from PHP
Version 5.

The problem I am having is that when I call an AD object, I get all
the data you would expect, however the logonHours do not always come
back; Or if they do they are not the same as that shown in thd LDIF
export file (I use this as my reference).

When and if I do succeed in getting the right data back, can anyone
tell me how to decode this back to times / days. I am sure I could
reverse engineer this data, given time, but if someone has already
done it, I would be most grateful.

I should be most grateful for any help regarding these items.

Can't help you here, I'm afraid...

Can you give an example of what form the data is in?

Logonhours is a 21 byte value with each bit representing 1 hour of the
week (i.e 3 bytes per 24hr day).

Unless PHP has some special variable type for handling 21 byte numbers
you'll have to play at bit setting and passing a block of data to the
user object.

I can give examples in Python and VB but not unfortunately in PHP.

<?php
function isBitSet($bitMask, $bitMap)
{
return (bool) gmp_intval(gmp_div(gmp_and($bitMask, $bitMap),$bitMask));
}
?>

Should be enough to get you going. :)
