The CAS and LDAP applications must connect to server via SSL channel for authentication.  CAS and LDAP servers used SSL server certificate issued by a publicly recognized certificate authority (CA).  In most cases, the client applications need not take care server certificate verification if it uses operating system managed CA certificates store in which the root CA certificate of CAS and LDAP server certificates has already included.  However, if the client application uses an user-managed CA certificates store, please take note that you have to import the below root CA certificate for successful verification of the CAS or LDAP server certificate.
