Check Text ( C-21777r485576_chk )
Check if the system is using NSS LDAP.
# grep -v '^#' /etc/nsswitch.conf | grep ldap
If no lines are returned, this vulnerability is not applicable.

Verify the permissions of the certificate database files.
# ls -lL /var/ldap/cert8.db /var/ldap/key3.db /var/ldap/secmod.db
If the permissions of any of the files contain a "+", and extended ACL is present, this is a finding.
Fix Text (F-21776r485577_fix)
Remove the extended ACL from the certificate database files.
# chmod A- /var/ldap/cert8.db /var/ldap/key3.db /var/ldap/secmod.db
