[Pkg-samba-maint] Bug#775108: samba: reverse DNS registration / creating associated PTR not working

[Andreas Meile]

Package: samba
Version: 2:4.1.13+dfsg-2
Severity: important

Dear Maintainer,

I set up a Samba 4 DC using "apt-get install samba" and then "samba-tool
domain provision" using SAMBA_INTERNAL - this worked fine. To enable
reverse DNS I use a

samba-tool dns zonecreate localhost 0.1.10.in-addr.arpa -U Administrator

which successfully creates a reverse DNS zone for my test network. The problem:
Dynamically registered domain member don't register the PTR record, only the
forward DNS record is updated. See details at

http://beilagen.dreael.ch/Diverses/Debian_8_Jessie_20150111_Samba_Reverse_DNS/

Create_forward_DNS.png: Even when set "Create assocatiated pointer (PTR)
record", the PTR is _not_ created as shown at Reverse_entry_test123_missing.png

Only when explicitely creating a PTR (Make_reverse_entry_explicitely.png) using
"Browse" (Make_reverse_entry_explicitely_using_Browse.png), then I get the
necessary PTRs as shown in Make_reverse_entry_explicitely_visible.png

To consider: In a original Microsoft ActiveDirectory environment, any host is
automatically registering as PTR as soon as the reverse DNS zone has been
created on the AD's DNS server(s).
