SSSD Dynamic DNS update failed - AD DNS does not accept the anonymous updates.

Solution Verified - Updated -

Issue

Dynamic DNS feature in SSSD fails to update the DNS entries.

In manual mode (using nsupdate), the two zones are updated, but in automatic, only the reversed zone is updated.

By referring to the following:
- 2.3. Enabling Dynamic DNS Updates

our sssd.conf file contains:

dyndns_update = true
dyndns_refresh_interval = 43200
dyndns_update_ptr = true
dyndns_ttl = 3600
