RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
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
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.
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?
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.
