Description Marko Myllynen 2011-09-08 12:24:51 UTC

Description of problem:
When running ipa-client-install on a system whose clock is not in sync with the master, kinit fails and enrollment is aborted. Manual checking of current time at the master and adjusting on the client-to-be is then needed.

It would be better to sync the time from the master before kinit to prevent this usability issue.

Version-Release number of selected component (if applicable):
RHEL 6.1 / IPA 2.1

fixed upstream

master: acb2c3106ad763a07eca6e0f6f6737c04f967bfe

Comment 6 Namita Soman 2011-10-17 17:47:40 UTC

Started with time on master at 13:45, and on client at 15:45

Ran ipa-client-install
debug logs indicate:
Synchronizing time with KDC...
root        : DEBUG    args=/usr/sbin/ntpdate -U ntp -s -b rhel62-server1.testrelm

.....where rhel62-server1.testrelm is the master IPA server.


after install, time on client matches master and is at 13:50

verified using ipa-client-2.1.2-2.el6.x86_64
