HI there,
I am using CAS 7.2.5 overlay, delegated authN via SAML. CAS delegates to
external IdP.
As seen below in
DelegatedClientAuthenticationDynamicDiscoveryExecutionAction, I store some
value in flow's conversation scope (part of "login" flow), BEFORE user gets
redirected to external IdP, I expect the objects are available in the same
conversation, but I find it is Null in
DelegatedClientAuthenticationWebflowStateContributor.
Via some debug code, i noticed that the conversation Id in
DelegatedClientAuthenticationWebflowStateContributor shows as Null, as part
of "clientredirect" flow.
Even though login and clientredirect flows are two separate flows, but they
are in the same conversation, I do Not understand why it shows Null for the
2nd part and object Not available.
thx!
