SAML Dynamic Attribute Mapping

Question

Hi, 
 We have configured SAML login in our environment but we are having trouble mapping the email attribute. Our client has two types of SAML users: 
 
 internal who have their email defined in the email claim. 
 external who do not have any value defined in the email claim, is empty when accessing Appian, and have their email in the name claim.

We are trying to find a way to make this mapping dynamic so it can work for both type of users with the same Idp. We need a way to validate if the email claim is empty and map the name claim instead, is this possible? 
 We haven't found any way to do this but we wanted to ask in case anyone knows or has any ideas that we can try. 
 
 Thanks in advance

Did you consider to create two separate configurations to the same IDP but with different mappings? When putting the two user groups into different Appian groups you can make them automatically use their respective login.

 Stefan&rsquo;s suggestion about creating separate configurations is a great starting point! If that&rsquo;s not feasible, here are a couple of other ideas:

Rule-Based Mapping at the IdP: If your IdP supports conditional logic, you could configure it to check if the email claim is empty. If so, fallback to using the name claim for the email attribute before sending it to Appian.

Middleware Preprocessing: If you have a middleware layer between the IdP and Appian, it could inspect the SAML assertion and adjust the claims dynamically (e.g., map name to email when the email claim is empty).
