Fixed In Version:	bind-dyndb-ldap-7.99-1.GIT158e95e.el7
Doc Type:	Known Issue
Doc Text:	The latest version of the bind-dyndb-ldap system plug-in offers significant improvements over the previous versions, but has some currently certain limitations. One of the limitations is missing support for the LDAP rename (MODRDN) operation. As a consequence, DNS records renamed in LDAP are not served correctly. To work around this problem, restart the named daemon to resynchronize data after each LDAP rename (MODRDN) operation. In an Identity Management (IdM) cluster, restart the named daemon on all IdM replicas.

Comment 1 Petr Spacek 2014-09-09 11:36:46 EDT

Know Issue text was added.

Comment 2 Martin Kosek 2014-09-11 06:27:45 EDT

2 comments to the Known Issue doc:

1) You should note that it needs to be restarted on *all IdM servers* with DNS service, not just the one where the change as done.

2) Isn't named reload enough (and more user friendly) than full named restart?

Good point! I have updated the text.

From bind-dyndb-ldap's point of view it is the same.

Comment 13 Abhijeet Kasurde 2015-10-08 06:02:24 EDT

Steps to verify :

1. Add a record to a zone
2. Verify that it is visible in DNS
3. Rename the record
4. Use dig to verify that renamed record is not visible in DNS under old name and is visible under the new name without requiring DNS restart

Verifed.
