SV-38976r1_rule If the system is using LDAP for authentication or account information, the LDAP TLS certificate authority file and/or directory (as appropriate) must not have an extended ACL.

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

Determine the SSL certificate key database file and/or directory. # grep -i '^ldapsslkeyf' /etc/security/ldap/ldap.cfg For each file or directory returned, check the permissions. # aclget < certpath > # aclget < certpath >/< certfile > If extended file permissions are enabled, this is a finding.

Fix text

Remove the extended ACL from the SSL certificate key database file. # acledit < certpath > # acledit < certpath >/ Disable the extended file permissions.

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.
