Summary     : The IPA authentication server
Description :
IPA is an integrated solution to provide centrally managed Identity (machine,
user, virtual machines, groups, authentication credentials), Policy
(configuration settings, access control information) and Audit (events,
logs, analysis thereof). If you are installing an IPA server you need
to install this package (in other words, most people should NOT install
this package).


How reproducible: most of time


Steps to Reproduce:
1. under ipa web ui: Identity -> DNS
2. select a zone for test, click "@" link
3. under CNAME section, crate a new cname record
4. after add new cname record success, click the same record and delete it.

---> result: it works sometimes, most of time it does NOT.
---> it seems like if i refresh the browser, it works most of time

Actual results:


Expected results:


Additional info: I suspect this is has something to do with cache somewhere --
not sure if that is on client side or server side.
