#Note: provider_conf_activate() is introduced in downstream only. It is a rewrite
#(partial) of the function provider_conf_load() under the 'if (activate) section.
#If there is any change to this section, after deleting it in provider_conf_load()
#ensure that you also add those changes to the provider_conf_activate() function.
#additionally please add this check for cnf explicitly as shown below.
#'ok = cnf ? provider_conf_params(prov, NULL, NULL, value, cnf) : 1;'
