If that works it means that you are not using SSSD on RHEL5 clients.
Please check your nsswitch and pam.conf to see what modules are actually
used.
Hmm. /etc/nsswitch.conf contains:
--------------------------
passwd: files sss ldap
shadow: files sss ldap
group: files sss ldap

And /etc/pam.d/system-auth contains:

i.e. they both contain both sss and ldap, with sss first. The client was installed with
the script generated by running "ipa-advise config-redhat-sssd-before-1-9" on
the server. This script contains:
# Use the authconfig to configure nsswitch.conf and the PAM stack
authconfig --updateall --enablesssd --enablesssdauth
and it also updates the /etc/sssd/sssd.conf file: So why would client not be
using sssd?
This only means that pam_sss/nss_sss fails and LDAP takes over and works.
You need to look at the sssd logs to see why it fails.
It probably does not find the right servers and falls though to LDAP.
Which RHEL5 versions do you use?
If memory does not fail me if you have SSSD 1.5 (I think it was starting 5.8)
you should be able to use ipa-client-install to configure sssd and pass the list
of the servers in the --server option.
Most of them are RHEL 5.11 with sssd 1.5.1. I'll try reinstalling and passing
the list of servers with the --server option.
