Title

If the system is using LDAP for authentication or account information, the LDAP TLS key file must have mode 0600 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. NOTE: Depending on the particular implementation, group and other read permission may be necessary for unprivileged users to successfully resolve account information using LDAP. This will still be a finding, as these permissions provide users with access to system authenticators.

Check Content

Determine if the system uses LDAP. If it does not, this is not applicable. # swlist | grep LDAP OR # cat /etc/nsswitch.conf | tr '\011' ' ' | tr -s ' ' | sed -e 's/^[ \t]*//' | grep -v "^#" | grep -i ldap If nothing is returned for either of the above commands, this is not applicable. If LDAP is installed, check the mode of the key file. # ls -lLa /etc/opt/ldapux/key3.db If the file permission is more permissive than 0600, this is a finding.

Fix Text

Change the mode of the file. # chmod 0600 <key file>
