The ability to specify the intermediate and Certificate Authority (CA) certificates to be used to validate a client certificate presented for login to the UI has been added to the API and to the Certificates & Security > WUI Access Options UI page. Controls have been added to the top of the page under Admin WUI Options that list all the intermediate and CA certificates currently installed on LoadMaster and allow you to select the certificate(s) that will be used to validate client certificates presented for login. Any client certificates presented whose chain of trust cannot be validated using the selected CA and Intermediate certificates will be denied access. The default is to check against all existing certificates.
