LDAP user password change fails

Hello All

I am setting up an RHEL 7 system to use solaris open ldap

Authentication is now working, however users get an error when trying to change there password;

[ldapuser@testserver ~]$ passwd
Changing password for user ldapuser.
Current Password:
New password:
Retype new password:
Password change failed. Server message: Error in search for entry "oid=1.3.6.1.4.1.4203.1.11.1,cn=features,cn=config".
passwd: Authentication token manipulation error

We actually hit this issue in the past and the workaround back then was to install pam_nss_ldapd and set up entries in /etc/pam_ldap.conf and /etc/pam.d/sssdproxyldap to point to the ldap servers see;

However this is Red Hat 7 pam_ldap.conf has now been deprecated been replaced with only sssd.conf.

Can anyone suggest another workaround?
