Check: GEN008260

SUSE Linux Enterprise Server v11 for System z STIG: GEN008260 (in versions v1 r12 through v1 r10)

Title

If the system is using LDAP for authentication or account information, the LDAP TLS certificate file must have mode 0644 or less permissive. (Cat II impact)

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>
