Description Alexey Tikhonov 2020-10-01 15:41:06 UTC

We have an asymmetrical auth scheme for DNS updates and wonder if sssd can add that?

For example:
```
dyndns_auth = GSS-TSIG
```
for A and AAAA records and
```
dyndns_auth_ptr = none
```
for PTR records.

* `master`
    * 0b069085cc6cb472b6c8841a26107ee1d48222ee - Add dyndns_auth_ptr support

Comment 5 Sumit Bose 2020-10-13 06:21:42 UTC

Hi,

to verify this feature please see https://github.com/SSSD/sssd/pull/5283#issuecomment-699824497

You can add the policy directly in named.conf for a stand-alone DNS server or use "ipa dnszone-mod  122.168.192.in-addr.arpa --update-policy='grant * tcp-self * PTR;'" for testing this with FreeIPA and the integrated DNS server.

HTH

bye,
Sumit
