I have no idea, mainly because it just works for myself :-(

adminuser at tmpdc1:~ $ sudo samba-tool dns add tmpdc1.samdom.example.com  samdom.example.com testdc A 192.168.1.8
Password for [administrator at SAMDOM.EXAMPLE.COM]:
Record added successfully

adminuser at tmpdc1:~ $ nslookup testdc
Server:		192.168.1.2
Address:	192.168.1.2#53

Name:	testdc.samdom.example.com
Address: 192.168.1.8

adminuser at tmpdc1:~ $ sudo samba-tool dns add tmpdc1.samdom.example.com  1.168.192.in-addr.arpa 8 PTR testdc.samdom.example.com
Password for [administrator at SAMDOM.EXAMPLE.COM]:
Record added successfully

adminuser at tmpdc1:~ $ nslookup 192.168.1.8
8.1.168.192.in-addr.arpa	name = testdc.samdom.example.com.

I know this not much help, but I suggest you double check everything.
