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

[Shree]

If you look at the attached logs, you can see it is going to the correct dns server. dig information is also correct. There is something else going on I can figure out what?

        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.

If it is getting to the wrong server then it is either looking at
    the wrong DNS server (see resolve.conf) which is telling it to use
    the wrong IPA server (may be from some old try/POC) or it has some
    explicit entries entered in /etc/hosts.

                  I have tested the port connectivity using telnet and
                  netcat commands but the install thinks these ports are
                  blocked?
