After configuring IDP for AzureAD I get the "UNABLE TO PROCESS REQUEST" whenever I try to run the IdpReactiveDemo.

The information I get from Service Center is the following:

Invalid request: no SAML message found.eSpaceVer: Id=10396, PubId=0, CompiledWith=

   at ssUsers.Flows.FlowSAMLAuth.ScrnIdP.Preparation(HeContext heContext)

The SAML message is there but SC still give the "no SAML message found" error.

Any idea what I can be doing wrong?

The configuration for AzureAD works with traditional web with no problem.

Hi Rui,

That URL it's for the built-in IdP component which is part of platform itself. The built-in IdP despite was based on the one in the forge it's not compatible with any IdP (SP side) forge components.

So, to use IdPReact you also need to use the "web" IdP forge component.
