I'd first try removing /etc/ipa/ca.crt and try the enrollment again. It
should be possible to use the 2.1.3 client in EL 5 to enroll against a
3.x server.

Otherwise we probably need more context from
/var/log/ipaclient-install.log to see how the CA was retrieved.

Thanks for the tip.  I tried it again, and it still failed.  End of the log:
