Description Striker Leggette 2020-07-07 16:37:32 UTC
[+] Description of problem:
 - During the ipa-client-install, nsupdate runs but tries to bind with GSSAPI. If the bind fails, nsupdate stops.

[+] How reproducible:
 - Always

[+] Steps to Reproduce:
 1. Run ipa-client-install.

[+] Expected results:
 - nsupdate tries to bind with gssapi but then tries unsecure if gssapi fails

Comment 2 Alexander Bokovoy 2020-07-08 05:08:40 UTC
This is by design. GSS-TSIG is the only way we can securely authenticate to the authorative DNS server at this point, we have no knowledge or means to do otherwise.

There are two places where a client might do nsupdate in FreeIPA domain:
 - during enrollment process, in ipa-client-install
 - during IP address changes in SSSD

SSSD has 'dyndns_auth' option that can be used to force insecure updates with 'none' value.

If we want to have any flexibility here, we probably need to retry nsupdate without GSS-TSIG if tsig version failed and then if that succeeded, set 'dyndns_auth = none' in SSSD configuration.
