'TLS - Truststore Password' - Password for the Truststore that is used when connecting to LDAP using LDAPS or START_TLS. 'TLS - Truststore Type' - Type of the Truststore that is used when connecting to LDAP using LDAPS or START_TLS (i.e. JKS or PKCS12). 'TLS - Client Auth' - Client authentication policy when connecting to LDAP using LDAPS or START_TLS. Possible values are REQUIRED, WANT, NONE.
