If you just set the forward (A) records, then no, you also have to set
the reverse (PTR) records in AD and tell your Windows clients to use
the reverse records.

You appear to be missing the reverse (PTR) records:

pi at rpidc1:~ $ host devstation
devstation.samdom.example.com has address 192.168.0.49
pi at rpidc1:~ $ host 192.168.0.49
49.0.168.192.in-addr.arpa domain name pointer
devstation.samdom.example.com.
