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

Determine the certificate file.
# grep -i '^tls_cert' /etc/ldap.conf
Check the permissions.
# ls -lL <certpath>
If the mode of the file contains a '+', an extended ACL is present. This is a finding.

Fix Text

Remove the extended ACL from the certificate file.

Procedure:
For each certificate file found remove all extended permissions.

# setfacl --remove-all <certpath>
