[Freeipa-users] ipa-client-install fails on replica because of kinit cannot contact any KDC

[Shree]

Hi
Attaching the install log. It complains about unable to reach certain ports, however my tests by using telnet were successful. Also to refresh your memory the client should be reaching for the replica lda2.mydomain.com and not ldap.mydomain.com which it does for the most part but I found a couple of instances of ldap.mydomain.com in the log. Let me know what you find. I can't believe I migrated over 40 servers and only this one refuses to install ipa-client.

Ok. I would guess you have some DNS issue. But it is hard to tell without the
entire ipaclient-install.log of the failed installation.
