SV-63249r2_rule If the system is using LDAP for authentication or account information, the LDAP TLS certificate file must have mode 0644 or less permissive.

Vulnerability 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 | grep -i “^tls” TLSCACertificatePath TLSCACertificateFile TLSCertificateFile For each TLSCACertificateFile and TLSCertificateFile defined in the configuration file, verify the file permissions: # ls -la 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

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
