samba - Jan 2014 - php script to migrate other attributes after running classicupgrade

Hi,

I have written a php script to upgrade a fresh s4 AD with more details 
from a (s3) ldap server. I am no programmer AT ALL, so I guess this is 
very dirty and un-elegant, but it does the trick.

We had multiple "mail" attributes in openldap, and since AD only
allows
1 mail attribute, additional mail addresses are migrated to 
"otherMailbox" AD attributes.

Perhaps someone else finds it useful as well. It should be easy to 
adjust for your own needs.

It requires apache2, php5 and php5-ldap.

Here it is:


<?php
