Looking more closely into this, it seems like Salesforce does not
support SAML logout.
In Salesforce, where I did the configuration for "SAML Single Sign-On
Settings", there is the following field:
Identity Provider Logout URL:
I had specified this as:
http://rashmiidp.cloud.com:9990/auth/realms/saml-demo/protocol/saml
But, since Salesforce does not seem to support SAML logout, is it
possible to specify some keycloak URL in this field that would logout
the user? It seems like the URL I specify in this field gets invoked but
then Salesforce is not really sending a SAML logout request and I just
get an error as indicated earlier. So, I was thinking if there is some
keycloak URL that we can specify in this field that would logout the user?
If there is no such URL support, is there an alternative to solve this
issue since Salesforce does not seem to handle the single logout?
Why do you draw the conclusion Salesforce does not support logout? That
does not seem to be indicated from this document:
