I'm installing ldap client on CentOS 7 hosts.  Some work, some do not. For those that don't work, I don't know why.  The install / setup process I used was the same on all hosts.  

yum install nss-pam-ldapd openldap-clients -y
authconfig --enableldap --enableldapauth --ldapserver=172.19.33.1 --ldapbasedn="dc=users,dc=domain,dc=com" --enablemkhomedir --update
systemctl start nslcd
getent passwd useraccount

The last command fails.  Vital signs on all hosts are fine, network, connectivity, ports, ntp, etc..

Where do I even begin troubleshooting the failure?

Thanks in advance.
