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

Check the permissions of the /etc/security/ldap/ldap.cfg file. Procedure: # aclget /etc/security/ldap/ldap.cfg Check to see if extended permissions are enabled. If extended permissions are enabled, this is a finding.

Fix text

Remove the extended ACL from the /etc/security/ldap/ldap.cfg file. # acledit /etc/security/ldap/ldap.cfg Disable 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.
