How to Remove First and Last Name Claims from SAML Responses in FusionAuth

[wesley]

We need to remove the firstname and lastname claims from the SAML response FusionAuth sends back to one of our applications. How can we do this?

You can remove claims from the SAML response using a SAML v2 populate lambda. For example:

samlResponse.assertion.attributes['firstName'] = null;
samlResponse.assertion.attributes['lastName'] = null;

Attach this lambda to your SAML Identity Provider configuration for that application.
