Description William Brown 2015-01-29 12:20:21 UTC 
Description of problem:
On a dual ipv4/ipv6 system, both with valid addresses. At initial install, IPA / sssd only creates the v4 record.

After the install, sssd attempts a DNS update. The following is logged.

[sdap_dyndns_dns_addrs_done] (0x0400): No DNS update needed, addresses did not change
[ipa_dyndns_nsupdate_done] (0x0040): DNS update finished

However, only the A record exists, the AAAA does not. As a result, the AAAA is never updated.

Deleting the IPV4 record and restarting SSSD yields:

 [sdap_dyndns_dns_addrs_done] (0x0400): Detected IP addresses change, will perform an update
 [be_nsupdate_create_fwd_msg] (0x0400):  -- Begin nsupdate message -- 
realm EXAMPLE.COM
zone example.com.
update delete yvett.example.com. in A
send
update delete yvett.example.com. in AAAA
send
update add yvett.example.com. 1200 in A 172.24.11.24
send
 [be_nsupdate_create_fwd_msg] (0x0400):  -- End nsupdate message -- 
 [write_pipe_handler] (0x0400): All data has been sent!
 [sdap_dyndns_update_done] (0x0400): No PTR update requested, done
 [ipa_dyndns_nsupdate_done] (0x0040): DNS update finished

However, only the v4 record is created. No PTR or AAAA is created. (This may be a different issue). Therfore delete / recreate is not a work around.

Version-Release number of selected component (if applicable):
sssd-client-1.11.2-68.el7_0.6.x86_64
freeipa-3.3.5

How reproducible:
Always
Comment 1 William Brown 2015-01-29 12:21:13 UTC 
Correction: Only the AAAA is not updated. The PTR is created.
Comment 3 Jakub Hrozek 2015-01-29 12:39:10 UTC 
At the moment, this is "expected". By default, we only update with the address that is read from the socket connecting to the LDAP server. The only alternative now is to specify the interface to update the addresses from.

We're aware this is suboptimal and we're planning to address this issue upstream, currently in the 1.13 milestone. I'll link this bugzilla with the upstream ticket.

Comment 5 William Brown 2015-01-30 04:35:21 UTC 
IE the work around is to provide:

dyndns_iface = eth0

And it will update A and AAAA?

I am going to try this as well. Perhaps this should be documented?
Comment 6 William Brown 2015-01-30 04:38:04 UTC 
zone example.com.
update delete yvett.example.com. in A
send
update delete yvett.example.com. in AAAA
send
update add yvett.example.com. 1200 in AAAA 2001:db8:0:11:5054:ff:feba:574
update add yvett.example.com. 1200 in A 172.24.11.24
send

This works correctly as a work around. Thanks.
