I have successfully configured SSO using SAML in Okta. Now, I wanted to configure Single Logout(SLO). In the SAML setting of the application, it is expecting "Signature Certificate" to upload. How I will get this Signature Certificate?
Thanks

I used the SP's CA certificate to send SLO.
Thanks for replying. Can you please let me know how to get this SP's CA certificate as I am now to Okta?
Thanks
In my scenario, SP is a firewall. So I downloaded the CA certificate from the inventory. As per the below document, you can either use device certificate or the CA certificate.

In my case, I have a simple Spring Boot application who is talking to Okta through SAML. SSO is working fine. But in case of SLO, it is logging out, but after, it is signing it again automatically. My intuition says that I am using wrong certificate while configuring SLO.
Any help is highly appreciated.
Thanks
I guess we have encountered a similar issue here 😅
Just check if the SLO is sent out using HTTP GET method instead of HTTP POST. Okta expects a HTTP POST as per their documentation. I am checking with my engineering team if we can send a POST.
But here I have another question too for OKTA team, if the SSO is supporting HTTP GET, then why HTTP POST for SLO ??
In my case, SLO("/saml/logout") is sending HTTP POST method with HTTP status of 302. Following this request, SSO request("/saml/SSO ") is executing(HTTP Status 200) and application signed in again automatically.
