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 group ownership of the ldap.cfg file. Procedure: # ls -lL /etc/security/ldap/ldap.cfg If the file is not group-owned by bin, security, sys, or system, this is a finding.

Fix text

Change the group owner of the /etc/security/ldap/ldap.cfg file to security, bin, sys, or system. Procedure: # chgrp security /etc/security/ldap/ldap.cfg

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.
