You can extend the AD schema, there is even a wiki page that might help:

What are these 'applications' ?
Perhaps someone is already using these applications with Samba AD.

Samba is a rapidly moving system and 4.3.11 is extremely old, also the
old ldap based Samba relies heavily on SMBv1 and Samba is working hard
on removing this.
You can if you so wish, keep version 4.3.x going, but as it is EOL from
the Samba point of view, you are unlikely to get much, if any, support
from Samba.

As I said, give us a bit more information about how you are using Samba
now (what applications are authenticating from Samba and how) and we
will try to help you upgrade.
