If LDAP authentication is not used on AIX, this is Not Applicable.
Note: Depending on which version of GSKit is installed on AIX, the GSK commands that are used to manage the Key Database (KDB) have different names. The possible GSK commands are: gsk8capicmd (used below), gsk8capicmd_64 and gsk7cmd.
Check if the system is using LDAP authentication:
# grep LDAP /etc/security/user
If no lines are returned, this requirement is not applicable.
Check if the useSSL option is enabled:
# grep '^useSSL' /etc/security/ldap/ldap.cfg
useSSL:yes
If "yes" is not the returned value, this is a finding.
Verify a certificate is used for client authentication to the server:
# grep -i '^ldapsslkeyf' /etc/security/ldap/ldap.cfg
ldapsslkeyf:/tmp/key.kdb
If no line is found, this is a finding.
Identify the Key Database (KDB), and its password, by asking the ISSO/SA. If no Key Database exists on the system, this is a finding.
List the certificate issuer with GSK command:
# gsk8capicmd -cert -list CA -db <KDB_FILE> -pw <KDB_PASSWORD>
Make note of the client Key Label:
# gsk8capicmd -cert -details -showOID -db <KDB_FILE> -pw <KDB_PASSWORD> -label <Key Label>
If the certificate is not issued by DoW PKI or a DoW-approved external PKI, this is a finding
The IBM GSK Database should only have certificates for the client system and for the LDAP server.
If more certificates are in the key database than the LDAP server and the client, this is a finding.
