Both the WebUI and the CLI on the RHEL server work fine. The issue is that I'm
trying to automate the cleanup of old PTR records for the IP address of a new
VM joining the domain (we're experimenting in an AWS Cloud environment and at
least in this phase we have RHEL6 machines joining the domain and then being
terminated on a regular basis).
I've found a workaround of sorts, but it relies on behavior that does not seem
"correct" to me, in the dnsrecord-mod command. For the standard case where
there's already exactly one PTR record for my IP, dnsrecord-mod is completely adequate.
For the edge case where there is more than one orphan PTR record matching my IP, I've
found that a dnsrecord-mod command formed so as to set the --ptr-hostname of any one of
the existing records to the empty string seems to have the effect of deleting all
matching PTR records except for the one specified, which is left untouched.
dnsrecord-mod --ptr-record=<any_old_hostname> --ptr-hostname="" <record_name>
This is correct and tested behavior :-)
I just forgot about it somehow.
So after this command, I seem to always have exactly one PTR record matching my
IP, which I can then change to the value I want with a second dnsrecord-mod
command.

The error I'm getting is that the option "raw" is invalid. The dnsrecord-del command includes a
"--raw" switch on RHEL6, but not on RHEL7. I am not using the switch, but according to the debug output,
RHEL6 is passing "raw" (as a parameter with a value) unconditionally, with the value indicating whether the
flag was selected or not. Since RHEL7 does not accept "raw", it fails.
Ah, I see. It looks like we broke forward compatibility of this command in
https://fedorahosted.org/freeipa/ticket/3503
I think dnsrecord-del should at least "eat" the options without raising error.
CCing Martin Basti to eventually create ticket for it. Martin, can you think of
any workaround that Anthony could use, besides using nsupdate?
I'm not aware of any workaround on that particular client side
Ticket filed: https://fedorahosted.org/freeipa/ticket/5644
Is there any issue that prevents you to use WebUI to remove dnsrecord,
or calling dnsrecord-del on RHEL7 machine (or directly on server)?

I hadn't thought about using the nsupdate tool, I'll give that a shot. Thanks.

I have a FreeIPA 4.2 server (on RHEL7) and a FreeIPA 3.0 client (on RHEL6). I

I'm trying to use ipa dnsrecord-del). I was just wondering if there is a
workaround that would allow me, from my 3.0 client, to delete a DNS PTR record
on the 4.2 server, since I can't use the ipa dnsrecord-del command (the APIs
are different, and the server responds that I've sent an invalid option).
Thanks.
That's strange, client should be forward compatible already:
http://www.freeipa.org/page/Client#IPA_management_tool
, i.e. RHEL-6 clients should be able to update RHEL-7 servers. We would know
more if you send us the error.
Anyway, given you are only updating DNS, maybe you could just use standard
Kerberos-authenticated DNS update (nsupdate tool), to delete that PTR record?
