Title

If the system is using LDAP for authentication or account information, the TLS certificate authority file and/or directory (as appropriate) must be group-owned by root, bin, sys, or other. (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. If LDAP is installed, check the group ownership of the LDAP cert file(s). # ls -lLd /etc/opt/ldapux # ls -lLa /etc/opt/ldapux/cert8.db If a certificate file or directory is not group-owned by root, bin, sys or other, this is a finding.

Fix Text

Change the group ownership of LDAP client certificate directory/files to root, bin, sys, or other. # chgrp root <directory> # chgrp root <directory>/<file>
