[Samba4] Updating DNS via Admin Tools fails on PTR record

So I've got samba4-alpha20 installed.  DNS integration with Bind 9.8.2 
via DLZ appears to be working (no named errors, newly added domain 
computer shows up).  I also created a reverse zone to match my forward 
with "samba-tool dns zonecreate"

Now I'm able to use the DNS admin tools in Windows 7 to add another 
forward record and it works fine.  But when I check the "Create 
associated PTR record" box, I don't see anything either in the Windows 
admin tool (for the reverse zone) or via nslookup.

I see a lot of "Failed DNS update" messages in the samba logs, but I'm 
not sure why.  Running /usr/local/samba/sbin/samba_dnsupdate --verbose 
seems to run fine, without errors (although it shows that there's 
nothing to update).

Here's an excerpt from my log.samba:
[2012/05/16 09:12:09,  0] 
   ../source4/dsdb/dns/dns_update.c:294: Failed DNS update - 
[2012/05/16 09:22:09,  0] 
   ../source4/dsdb/dns/dns_update.c:294: Failed DNS update - 
[2012/05/16 11:33:15,  0] 

Any advise on how to troubleshoot?  Or is this known not to work at this
