title: 'Configure Certificate Directives for LDAP Use of TLS'


description: |-
    Ensure a copy of a trusted CA certificate has been placed in the file
    <tt>/etc/pki/tls/CA/cacert.pem</tt>. Configure LDAP to enforce TLS use and
    to trust certificates signed by that CA. First, edit the file
    <tt>/etc/nslcd.conf</tt>, and add or correct either of the following lines:
    <pre>tls_cacertdir /etc/pki/tls/CA</pre> or 
    <pre>tls_cacertfile /etc/pki/tls/CA/cacert.pem</pre>
    Then review the LDAP server and ensure TLS has been configured.

rationale: |-
    The tls_cacertdir or tls_cacertfile directives are required when
    tls_checkpeer is configured (which is the default for openldap versions 2.1 and
    up). These directives define the path to the trust certificates signed by the
    site CA.
