I am having trouble setting a user attribute in AD to nothing with Kix.
Still running 4.22

I can set the attribute to any text, but get errors trying to set it to nothing.

$adsUser.postOfficeBox = ""
$adsUser.setinfo

will not work.

$adsUser.postOfficeBox = "New Text"
$adsUser.setinfo

This comes back error free and changes the field to "New Text".

What am I not seeing here ?

Thanks
