Hi Andy,

Thanks for looking my problem.
I'm not sure the problem is the OIDC authentication protocol.

Here are my tomcat logs (I anonymise my logs):

The IDP OIDC is the CAS 5.3.7 OIDC and the IDP SAML2 is the IDP where I 
delegate the authentication

*LOG tomcat about the authentication OIDC without delegation SAML2*

I see that during the OIDC authentication without delegation SAML2 the 
p3/serviceValidate is called but not with the delegation SAML2.
I think the problem occured when the IDP-SAML2 send the response to the 
IDP-OIDC.
