SAML request could not be determined from the authentication request

[Mohamed Amdouni]

Hello,

We are encoutering this exception : "SAML request could not be determined from the authentication request"

Description of the flow :

1- Third Application that includes iFrame 

2- the iFrame contains the SP (the application secured by CAS with SAML2 protocol)

When calling the SP within the iFrame, the exception is encountered.

- When calling the SP on the browser, it works fine.

How to deal with SPs integrated within iFrames?

Thanks.

Best Regards.
