Fixed In Version: ipa-3.0.0-1.el6
Doc Type: Bug Fix
Doc Text:
Cause: Identity Management DNS module use "pull" model for updating DNS records provisioned to BIND Nameserver by bind-dyndb-ldap plugin. Consequence: When a DNS zone LDAP entry or DNS records present in bind-dyndb-ldap cache are changed via Identity Management CLI or Web UI, the update is not provisioned to the BIND nameserver until a zone is checked with a periodic poll or the DNS record in cache expires. Fix: Enable persistent search by default for both new Identity Management installations and for running Identity Management server instances. Result: A change to DNS zone LDAP entry or to DNS record that is already cached by bind-dydnb-ldap is instantly provisioned to the BIND Name server and thus resolvable.

Description Rob Crittenden 2012-05-07 15:14:11 EDT 
This bug is created as a clone of upstream ticket:
https://fedorahosted.org/freeipa/ticket/2719

Persistent search will be needed by DNS SOA serial number update/zone transfer support (IPA 3.0) and DNSSEC (IPA 3.1), as discussed on meeting May/03/2012.

During upgrade it's necessary to modify "dynamic-db ipa" section in /etc/named.conf configuration file and make sure that this line is present:

{{{
arg "psearch yes";
}}}

Old configuration file can contain old value "psearch no" or psearch line value can be missing completely, before the IPA upgrade.
Comment 1 Martin Kosek 2012-06-12 03:18:26 EDT 
Fixed upstream:

master:
c856fb60737612781fab30760bceeb8bbf6312d9
ce97d6f8e7cb47927fccc27c258d32caf895a88c
1d44aba89b225aa9e131ac8ca596df7b0faaa964

Persistent search is now enabled by default both for new IPA installations and for running IPA server instances.

Existing IPA server instance psearch features is enabled only once, i.e. when psearch is turned off during RPM update and then turned off by user, subsequent RPM updates won't turn it back on.

ipa version:

ipa-server-2.2.0-16.el6.x86_64

ipa-server-3.0.0-8.el6.x86_64

how to verify:

1.create a rhel6.3 beaker machine installed with ipa server 2.2.0-16
2.[root@sgi-xe320-01 ~]# cat /etc/named.conf |grep psearch 

nothing in named for persistent search,i.e.psearch line value is missing completely
3.update ipa server to newest version 3.0.0-8

4.[root@sgi-xe320-01 yum.repos.d]# cat /etc/named.conf |grep psearch
	arg "psearch yes";
  
verified that psearch line exists in named.conf after upgrade
