ISE - Certificate Portal Guest

[Kalimoz]

Hello all,

I have a standalone deplyment in ISE, with all the certificates installed in them. So there is no problems with certificates in browser when access to the platafform and trust with eatch other.

My problem is with the Portal Guest. Everytime the page is open, i always get the error with certeficate, what can i do to resolve this issue?

ISE does a background redirection from the guest/sponsor portal to the admin portal that will make a decision of which PSN is going to serve that session before the session is redirected back to the PSN. If the admin portal FQDN/IP is not added to the used cert, you will get that error. You can easily check that out by enabling the browser inspection.

Hello Aref,

Thank you for your reply

To add the FQDN to the cert do i need to issue a new one into the ISE or can i just add it to the ones that i have created before?

You welcome. You need to go through the cert generation process again adding the new FQDN(s) into the SAN list.

Hi,

What certificate have you selected for the guest portal.? Whatever you use
as guestportal URL should be listed in your guest certificate (CN or SAN).
If you have wildcard certificate, then make sure that guest portal URL is
part of subdomains. All that said, I am assuming that you are using CA
signed certificate.
