Yup, you're right:

Ok, this is going to sound weird, but it should work.

Register a logout URL for keycloak at salesforce.com as

http://rashmiidp.cloud.com:9990/auth/realms/saml-demo/protocol/openid-connect?redirect_uri=<encoded-url>

Replace <encoded-url> as a URL encoded version of the URL you want keycloak to redirect the browser after logout.

Next, you'll have to go into the Client tab in the Keycloak admin console and add that redirect uri to the list of allowed redirect uris.   This is a bit of a hack, but it should work.

When I do a logout, my SAML tracer show this request:

GET http://rashmiidp.cloud.com:9990/auth/realms/saml-demo/protocol/saml HTTP/1.1

And clicking this request just shows the HTTP tab. It does not even show the SAML tab. So, it looks like Salefroce does not send SAML request for logout. That was the reason, I was asking if there is another way to do the user sign out from keycloak. That is, in instead of the above URL we use a different url (some keycloak URL) that would sign out the user. Or some other alternative?

My guess is that Salesforce is not signing the logout request and Keycloak expects it to be signed, but can't really know unless you post your SAML tracer. Also,  Edit your standalone.xml config file (really depending on how you've booted keycloak).  Search for "logging:3.0".  IN that section, turn on debug logging for keycloak:

            <logger category="org.keycloak">
                <level name="DEBUG"/>
            </logger>

That may shed some light on things.

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:

http://resources.docs.salesforce.com/202/18/en-us/sfdc/pdf/salesforce_single_sign_on.pdf

What is the SP metadata you used?
