[keycloak-user] trouble acting as SP with testshib.org IdP

Hi Steve,

I spent some time in order to integrate into Renater federation (french
research shibbolet federation) because keycloak does not handle the
discovery service that parse the WAYF...
So I have develop a small apps to parse this file and synchronize my 250
IdP into keycloak !! I also customize the template in order to build a
choice list taking info from my discovery app.
Next step for me is to fork the saml provider of keycloak to built a
dedicated shibboleth one.
You probably faced some issues about transient nameid because shibboleth
federation does not give a persistent nameId but a transient one and
because keycloak need to associate the IdP/nameId to a real keycloak
account, transient nameid result in new account for each new shibboleth IdP
session...
You have to rely on an attribute eduPersonTargetedID but this attribute is
a complex type and keycloak SAML attribute parser can't handle it
correctly. I have make a small patch also to avoid problem with that and to
ensure the mapping between this attribute and the nameID.

By the way, I'm intrested if you succeed in order to share some tips and to
enlarge knowledge base about those aspects around Shibboleth and keycloak.

Best regards, Jérôme.
