Map SAML attributes to user_metadata attributes via action

[dnationalwala]

The following page mentions how we can map user_metadata to saml response

Map SAML attributes to user_metadata attributes

Problem statement Our enterprise connection, SAML provider, returns custom attributes like Firstname and Lastname. We want them to be mapped to user_metadata.first_name and user_metadata.last_name. How do I do this? Solution The “Mappings” tab ( Auth0 Dashboard > Authentication > Enterprise > SAML > Your SAML Connection > Mappings ) cannot be used to map the attributes in SAML Assertion to the user_metadata. For example, the following mappings won’t work: { "user_metadata.first_name": "ht…

however as rules are going to be deprecated, how do we write action to accomplish this?

I’m also interested in this question. I have tried setting up Actions to do this, but could not get it to work.

In my specific case, I am trying to get a hard-coded value in Auth0’s SAML response when Auth0 is the IDP, but can’t make it work.

I’m following How to Map SAML Attributes when Auth0 is the IDP in the SAML2 Addon,
specifically case 5 (“Mapping hard-coded values that don’t exist in the user profile to the SAML Response”), but instead of a Rule I’m using an Action as such:

exports.onExecutePostLogin = async (event, api) => {
  event.user.saml_mapping_helper_bool_true = "true";
};

In my Auth0 App, I have SAML enabled with the following settings (I’m showing only the subset that matters below):

{
  "mappings": {
    "email": "User.Email",
    "name": "User.FirstName",
    "saml_mapping_helper_bool_true": "User.EmailNotifications"
  }
}

I’ve double checked this action is applied in the Login flow. I also tried mapping saml_mapping_helper_bool_true to “User.FirstName” instead
because I had verified that User.FirstName works in the SP, but it still doesn’t pick it up.

I wonder what I’m missing here.
