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?

This is a generic error and does not give any clue.

I used SAML tracer with firefox and there I see the following request in RED:

Hi,

I have setup a Salesforce Saml SP in keycloak. So, I basically created a
new client from keycloak admin console for salesforce. This is how my SP
url looks like:

rashmi789-dev-ed.my.salesforce.com
 <http://rashmi789-dev-ed.my.salesforce.com>

I edited the salesforce configuration settings to point it to the
keycloak IDP. So, when I access the SP:
http://rashmi789-dev-ed.my.salesforce.com

I am successfully taken to the keycloak IDP page (where I have
configured my Authenticator). I enter my credentials there and am able
to login. But, now when I try to logout, I get the following error on
the web page:

We're sorry ...
Invalid Request

Is logout supported on both ends (i.e. SP and IdP)? The definition of support is in the metadata of each entity. Is there a SingleLogoutService binding with a valid location URL in each metadata? The vast majority of SAML problems are directly attributable to the metadata because that is what drives the conversation between the SP and IdP. You have access to both metadata because it was necessary to load the metadata in each party.

If the problem is not the absence of SingleLogoutService then I would try tracing the flow. That is easy with the Firefox browser and the SAMLTracer add-on. That will let you see the exchange of messages and identify who the offending party is.

So, single sign out does not seem to be working for me. What is the
issue? Is it a problem with the IDP logout url that I have configured?
What I have is:

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


my IDP Login URL is:
http://rashmiidp.cloud.com:9990/auth/realms/saml-demo/protocol/saml

and that seem to be perfectly fine as I am able to login without any
issue. what is the issue with the logout I am seeing above when using a
Salesforce SP with keycloak? Please let me know if you need me to
provide more details.

 This suggests the problem is not with the IdP. Keycloak uses the same URL for all services (don't assume this is always the case, it's just one implementation choice). If login to the same URL works a valid LogoutRequest to the same URL should also work, provided of course it a valid SAML Request. Are there any errors in the Keycloak log concerning invalid requests.

Once again. using SAMLTracer will help nail down who is generating the error and what the content of the message was that induced it.


Also, once this issue is resolved and I am able to logout successfully,
could you give some insights on how to customize the logout page?
