`ProviderID` isthe service provider identifier, this field will often be filled with `lasso_login_init_authn_request()`

`nameIDPolicy` tells the identity provider about the policy to use for federation; it must be one of LASSO_LIB_NAMEID_POLICY_TYPE_NONE, LASSO_LIB_NAMEID_POLICY_TYPE_ONE_TIME, LASSO_LIB_NAMEID_POLICY_TYPE_FEDERATED or LASSO_LIB_NAMEID_POLICY_TYPE_ANY.

`IsPassive` ; if `TRUE` (default) it tells the identity provider not to interact with the user.

`ForceAuthn` ; only used if `IsPassive` is `FALSE`, it tells the identity provider to force authentication of the user even when already authenticated.

`ProtocolProfile` is the Single Sign-On and Federation profile to adopt; either LASSO_LIB_PROTOCOL_PROFILE_BRWS_ART (which is the default value) or LASSO_LIB_PROTOCOL_PROFILE_BRWS_POST.
