[Freeipa-users] Configuring RHEL 5 clients for automatic failover of servers

Hmm. /etc/nsswitch.conf contains:

--------------------------
passwd:     files sss ldap
shadow:     files sss ldap
group:      files sss ldap
--------------------------

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

--------------------------
auth        required      pam_env.so
auth        sufficient    pam_unix.so nullok try_first_pass
auth        requisite     pam_succeed_if.so uid >= 500 quiet
auth        sufficient    pam_sss.so use_first_pass
auth        sufficient    pam_ldap.so use_first_pass
auth        required      pam_deny.so

account     required      pam_unix.so broken_shadow
account     sufficient    pam_succeed_if.so uid < 500 quiet
account     [default=bad success=ok user_unknown=ignore] pam_sss.so
account     [default=bad success=ok user_unknown=ignore] pam_ldap.so
account     required      pam_permit.so

password    requisite     pam_cracklib.so try_first_pass retry=3
password    sufficient    pam_unix.so md5 shadow nullok try_first_pass use_authtok
password    sufficient    pam_sss.so use_authtok
password    sufficient    pam_ldap.so use_authtok
password    required      pam_deny.so

session     optional      pam_keyinit.so revoke
session     required      pam_limits.so
session     [success=1 default=ignore] pam_succeed_if.so service in crond quiet use_uid
session     required      pam_unix.so
session     optional      pam_sss.so
session     optional      pam_ldap.so
--------------------------

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?

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.
