Check: GEN008160

SUSE Linux Enterprise Server v11 for System z STIG: GEN008160 (in versions v1 r12 through v1 r9)

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 system. (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 the certificate authority file and/or directory. # grep -i '^tls_cacert' /etc/ldap.conf For each file or directory returned, check the group ownership. # ls -lLd <certpath> If the group-owner of any file or directory is not root, bin, sys, or system, this is a finding.

Fix Text

Change the group ownership of the file or directory. # chgrp root <certpath>
