Discussion

LDAP can be used to provide user authentication and account information, which are vital to system security. The LDAP client configuration must be protected from unauthorized modification.

Check Content

Identify the LDAP TLS Certificate file:

# cat <ldap_config_file> | grep -i “^tls”

TLSCACertificatePath <path>
TLSCACertificateFile <filename>
TLSCertificateFile <filename>

For each TLSCACertificateFile and TLSCertificateFile defined in the configuration file, verify the file permissions:

# ls -la <tls_certificate_file>

If the mode of the file is more permissive than 0644, this is a finding.

Fix Text

Change the mode of the file:

# chmod 0644 <certpath>
