Title

If the system is using LDAP for authentication or account information the /etc/ldap.conf (or equivalent) file must have mode 0644 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.

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. Check the permissions of the LDAP configuration file(s). ls -lL /etc/opt/ldapux/ldapux_client.conf /etc/opt/ldapux/ldapclientd.conf /etc/opt/ldapux/ldapug.conf If the mode of the file is more permissive than 0644, this is a finding.

Fix Text

Change the permissions of the file. # chmod 0644 <LDAP configuration file>
