Your LDAP client should now be pointing to the LDAP server. Test it by running the id

ldapuser1 command:

# id ldapuser1

uid=500(ldapuser1) gid=500(ldapuser1) groups=500(ldapuser1)

context=root:system_r:unconfined_t:s0-s0:c0.c1023

In RHEL 6, you can no longer authenticate over SSH without using TLS. This section has not

described how to set up TLS. To perform that setup, you need a signed certificate that

corresponds to your enterprise’s DNS domain name. Refer to the OpenLDAP website at the

following address for more information:

http://www.openldap.org/pub/ksoper/OpenLDAP_TLS.html

More details about the cn=config/ directory replacing the /etc/openldap/slapd.conf file can

be found at the following Red Hat website (you need a subscription to get to it):
