Check Text ( C-36831r1_chk )
Check if the system is using NSS LDAP. # grep -v '^#' /etc/nsswitch.conf \| grep ldap If no lines are returned, this vulnerability is not applicable. Verify a server certificate is required and verified by the NSS LDAP configuration. # grep -i '^tls_checkpeer' /etc/ldap.conf If no line is returned, or the value is not "yes", this is a finding.

Fix Text (F-31669r1_fix)
Edit "/etc/ldap.conf" and add or set the "tls_checkpeer" setting to "yes".
