Looking at debug this is what I see:

< HTTP/1.1 401 Authorization Required
< Date: Tue, 26 Feb 2013 16:54:21 GMT
< Server: Apache/2.2.15 (CentOS)
* gss_init_sec_context() failed: : Server krbtgt/c...@example.com not found in 
Kerberos database< WWW-Authenticate: Negotiate

krbtgt/c...@example.com is definitely not correct. It should look like "krbtgt/example....@example.com". I would recommend to double check name resolution.

Are all records in /etc/hosts correct?

Does /etc/resolv.conf point to the IPA server?

Do forward (A) and reverse (PTR) records match for client and also IPA servers?

Does dig -t TXT _kerberos.example.com return correct REALM?

Do all domain and realm names in /etc/krb5.conf point to correct IPA domain?

You can run ipa-client-install with KRB5_TRACE environment variable set. It could produce some useful output. E.g.:

$ KRB5_TRACE=/tmp/kerberos_trace.log ipa-client-install <.. blah blah..>

This should log actions done by Kerberos libraries to file /tmp/kerberos_trace.log.

Also, "tcpdump -s 65535 -w /tmp/tcpdump -i any" could provide some clue.

You can send both files to me privately if you don't want to send them to mailing list.

FYI, I have this same issue when enrolling RHEL5 clients. Have been
doing this as a workaround:

        wget -O /etc/ipa/ca.crt http://ipa1.example.com/ipa/config/ca.crt
        ipa-client-install --no-ntp --mkhomedir --ca-cert-file=/etc/ipa/ca.crt
