I am not sure at 100% and didn't try, but it seems that what you need is mapper of type "Username template importer" (corresponding Java class is org.keycloak.broker.saml.mappers.UsernameTemplateMapper ) and you configure the template attribute with value:
ATTRIBUTE.mail

Hope it helps,

Hi All,

I am trying to connect Shibboleth IdP as an external IdP with Keycloak acting as an SP. 
I get the email of the user with friendly name as "mail" back in the SAML assertions. I want to set this as my username for this user in Keycloak. 

I am attaching a screenshot of my configurations for the mappers which is not working. Maybe someone might have resolved this already or know how to solve it? 

Thanks,
Robin
