Hello,
somehow a call to /myApp?GLO=true now seems to do the trick and behaves as expected:
sending a logout request to the kc-idp.
I must have messed up any other configuration back when I tried it only with this setup.
(I used to call HttpServletRequest.logout() and resp.sendRedirect(contextPath +
"?GLO=true") since only redirecting to contextPath + "?GLO=true" did
not work back then ) .
There STILL is something I have not figured out. I am STILL getting a 403 Forbidden when
the browser posts the logoutresponse with
<samlp:StatusCode Value="urn:oasis:names:tc:SAML:2.0:status:Success"/>
Back to the /saml endpoint in my application and I get redirected to a page with the
content
<html><head><title>Error</title></head><body>Forbidden</body></html>
Isn't the client handling LogoutResponses? What can I do about it?
Regards,
Manuel Waltschek

Betreff: Re: [keycloak-user] KEYCLOAK SAML logout not working as documented
Hello,
since the doc says : " For any other browser application, you can point the browser
at any url of your web application that has a security constraint and pass in a query
parameter GLO",
could it be, that I need to point the browser to a protected ressource that is not only
protected, but also not accessible for the current role?
I guess
org.keycloak.adapters.saml.profile.webbrowsersso.WebBrowserSsoAuthenticationHandler.handleRequest()
is only called, if the ressource needs authentication, but when I am logged in already
with the security constraint
<security-constraint>
<web-resource-collection>
<web-resource-name>The protected resources</web-resource-name>
<url-pattern>/*</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>*</role-name>
</auth-constraint>
<user-data-constraint>
<transport-guarantee>NONE</transport-guarantee>
</user-data-constraint>
</security-constraint>
it is not triggered and therefore there is no call to
org.keycloak.adapters.saml.profile.webbrowsersso.WebBrowserSsoAuthenticationHandler.globalLogout()

Hello and thank you Bjoern for your answer, unfortunately…
… it also behaves like this when I implement it in a logout servlet.
What does „being marked as logged out“ actually mean?
Please help me resolve this issue,
thank you in advance and best regards,

Hello Manuel,
please refer the documentation:
https://www.keycloak.org/docs/latest/securing_apps/index.html#_servlet_fi....
When you work within a servlet filter it will act as the same.
In case of a java servlet filter client adapter the backchannel logout work different!
Instead of invalidating the session, you will be marked as logged out.
In your case, implement the logout inside your code which is in the application server
like the web application and NOT in an external filter.
With best regards,
Bjoern

Hello KC Community,
I am still trying to find out how to properly logout from keycloak using the kc adapter on
wildfly10.
Documentation says
3.1.8. Logout
There are multiple ways you can logout from a web application. For Java EE servlet
containers, you can call HttpServletRequest.logout(). For any other browser application,
you can point the browser at any url of your web application that has a security
constraint and pass in a query parameter GLO, i.e.
http://myapp?GLO=true<http://myapp/?GLO=true>;. This will log you out if you have an
SSO session with your browser.
As HttpServletRequest.logout() in Undertows implementation
io.undertow.servlet.spec.HttpServletRequestImpl checks isInvalidateSessionOnLogout returns
false in my case it does not much.
@Override
public void logout() throws ServletException {
SecurityContext sc = exchange.getSecurityContext();
sc.logout();
if(servletContext.getDeployment().getDeploymentInfo().isInvalidateSessionOnLogout()) {
HttpSession session = getSession(false);
if(session != null) {
session.invalidate();
}
}
}
Im calling HttpServletRequest.logout() in a ServletFilter implementation, but it does not
end the keycloak session and I can still reach protected ressources. There is no
backchannel request as I would expect.
When I do the following:
private void requestGlobalLogout(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
String contextPath = req.getContextPath();
req.logout();
resp.sendRedirect(contextPath + "?GLO=true");
it somehow works, but sends another AuthnRequest before sending the LogoutRequest. Then
the LogoutResponse ist posted to myapp/saml again which leads to http Status code 403
forbidden.
Please also see:
https://issues.jboss.org/browse/KEYCLOAK-2191
and https://lists.jboss.org/pipermail/keycloak-user/2017-July/011207.html
