ISE 3.4 P3 - Can't to bypass ISE Web portal with SAML integration

Mafra — Thu, 20 Nov 2025 17:16:58 GMT

Hello team!

I configured a SAML integration with ISE and the authentcation and authz is working just fine.

Now I am trying to fine tune it so ISE does not present its web portal and gets the client straight to the SAML web page, but I am not being able to stop ISE from presenting its own portal.

Any ideia of how to do this?

Guest portal flow:

Client gets redirect to ISE portal with the option to login with the external (SAML) portal:

Web page after pressing at the SAML portal, I would like the client to go straight to this page instead of having to press at the option in ISE portal:

What does your portal configuration look like? When I configure the SAML IdP as the Authentication method for my Guest portal as per this example, I do not see this behaviour.

Hi!

Found the problem. The SAML integrator config was opening a portal customized that looks just like the ISE Portal. I didn’t have access to the URL, only an image of the web portal, so that’s why I didn’t catch it earlier.
