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

[Niels Bertram]

Hi guys,

I have a requirement to map a user email to the /saml:Subject/saml:NameID
field in a Keycloak SAML client. I can see that someone else is asking for
the same at
http://stackoverflow.com/questions/39854398/sending-username-emailid-in-the-saml-req-as-nameid-to-keycloak
without much luck. The mapper only maps attributes while I need to change
the subjects identifier.

Could anyone help with a thought on how that can be achieved?

Many thanks,
Niels
