[keycloak-user] Map SAML Subject NameID to user email

[Niels Bertram]

Hi Jared,

setting the Name ID Format does not set the NameID field value to the email
address of the user model. Whatever I set it to, the only value I can see
in the SAML response is the realm users username.

Thanks for pointing to the persistent Name ID configuration. Just to
confirm, to make this work, one will also have to configure a Property
Mapper in the SAML Client configuration with following details:

Protocol:                  saml
Name:                      Swap NameID username for email
Consent                    Required: off
Mapper Type:               User Attribute
User Attribute:            email
Friendly Name:             Email
SAML Attribute Name:       saml.persistent.name.id.for.$clientId
SAML Attribute NameFormat: Unspecified


Does that look about right?

Thanks,
Niels
