Title

If the system is using LDAP for authentication or account information, the /etc/ldap.conf (or equivalent) file 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. Check the group ownership 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 any of the above files are not group owned by root, bin, sys, or other, this is a finding.

Fix Text

Change the group owner of the file to root, bin, sys, or other. # chgrp root <LDAP configuration file>
