What is the exact use of this bellow entry in WAS6.1 server.xml. Can you please tell me why we need this "defaultCookieSettings" and his attribut "secure=false".
defaultCookieSettings xmi:id="Cookie_1282579260990" domain="" maximumAge="-1" secure="false"
<components xmi:type="applicationserver.webcontainer:WebContainer" xmi:id="WebContainer_1282579260990" enableServletCaching="false" disablePooling="false">

<invalidationSchedule xmi:id="InvalidationSchedule_1282579260990" firstHour="14" secondHour="2"/>
</tuningParams>
</services>
</components>
If I change into from secure="true" then what will be the impact
The setting will specify that the session cookies include the secure field. Enabling the feature restricts the exchange of cookies to HTTPS sessions only.

I have a subflow that ensures an OAuth access token is current. The token value is saved in an object store that expires the entry shortly before it times out. When expired, a new token value is retrieved and placed in the object store.
I didn't find any straightforward examples of a Mule v3 methodology to refresh a token that utilizes an object store, so here's the code, if anyone's interested.
<sub-flow name="get_token">
<objectstore:retrieve config-ref="TokenStore" key="StatusToken" defaultValue-ref="#['expired']" targetProperty="StatusToken" doc:name="Get token from Object Store"/>
<choice doc:name="Expired?">
<when expression="#[flowVars.StatusToken == 'expired']">
<set-payload value="#[{'grant_type':'refresh_token', 'refresh_token':'${RefreshToken}'}]" doc:name="Set payload for token refresh"/>
<http:request config-ref="HTTP-Token" path="${tokenPath}" method="POST" doc:name="Get new token">
<http:request-builder>
<http:header headerName="Content-Type" value="application/x-www-form-urlencoded"/>
</http:request-builder>
</http:request>
<dw:transform-message doc:name="Write token to flowVar">
<dw:set-variable variableName="StatusToken">
<![CDATA[
%dw 1.0
%output application/java
---
payload.access_token
]]>
</dw:set-variable>
</dw:transform-message>
<objectstore:store config-ref="TokenStore" key="StatusToken" value-ref="#[flowVars.StatusToken]" doc:name="Put token to Object Store"/>
</when>
<otherwise>
<set-variable variableName="Useless" value="#['']" doc:name="Useless placeholder"/>
</otherwise>
</choice>
</sub-flow>
The flow works well as designed, but here's my question. A choice router checks to see if the token has expired. There is no action required otherwise, and the flow errors out if the default path is empty. What's the simplest element to minimize processing and any resource utilization on the default path?
Following Ryan Carter's comment, this could be marked as a duplicate, but not really.
Here's the link:
How do I implement IF in mulesoft
Summary
Mule 4:
The <otherwise> tag is not needed
Mule 3:
A component is needed. I tend to use Logger with the level of TRACE, since log4j2 is smart and won't substitute parameters if the level is set to DEBUG and higher. However, if you really need to debug a flow, it would be good to see that it got routed correctly.
I've an issue on this feature.
SignIn action works well with ADFS and return to AuthServices/Acs
But Logout action don't call ADFS and redirect directly to returnUrl parameters (checked it with fiddler).
I'm calling this link : /AuthServices/Logout?ReturnUrl=~/&Status=LoggedOut
web.config is set up as this :
<kentor.authServices entityId="https://localhost:2181/AuthServices" returnUrl="https://localhost:2181/">
<identityProviders>
<add
entityId="https://ADFS DOMAIN/adfs/services/trust"
signOnUrl="https://ADFS DOMAIN/adfs/ls"
logoutUrl="https://ADFS DOMAIN/adfs/ls/?wa=wsignout1.0"
binding="HttpPost"
allowUnsolicitedAuthnResponse="true"
metadataLocation="https://ADFS DOMAIN/FederationMetadata/2007-06/FederationMetadata.xml"
wantAuthnRequestsSigned="true">
<signingCertificate fileName="~/App_Data/*****.cer" />
</add>
</identityProviders>
</kentor.authServices>
If I launch https://ADFS DOMAIN/adfs/ls/?wa=wsignout1.0 on another tabs, it is working, I return on signin page from my website.
So it seems to be an internal issue to retrieve logouturl and send it ?
Thanks for helps.
There are a number of requirements that need to be met before logout request will be issued:
You need to have a http://kentor.se/AuthServices/LogoutNameIdentifier claim and its issuer has to match the IDP that you're trying to logout from.
You need to have http://kentor.se/AuthServices/SessionIndex claim.
Your AuthServices IDP configuration needs a logoutUrl (I see you've specified this but probably it's easier to let AuthServices read it from the metadata)
You have specified a ServiceCertificate with either Signing or Both usage (i.e. not just Encryption)
Your AuthServices IDP configuration has DisableOutboundLogoutRequests =
false (this is the default)
Missing claims (first two points) is the most likely issue if you have some claims transformation happening during login or you are not retaining the original ClaimsIdentity. See also the documentation regarding ClaimsAuthenticationManager, e.g. https://github.com/KentorIT/authservices/blob/master/doc/ClaimsAuthenticationManager.md
You can turn on logging and see which of these points are failing:
https://github.com/KentorIT/authservices/blob/v0.21.2/Kentor.AuthServices/WebSSO/LogOutCommand.cs#L155-L170
I'm wading through the creation of a claims-based MVC site in Visual Studio 2013.
Some things I learned so far:
System.Identity is in, Microsoft.Identity is out
Many of the tutorials, including Microsoft's guides for 4.5, are out-dated. For example, I don't believe any changes to the Project Template-generated .config file are necessary for adding modules/handlers or anything.
There is no Microsoft built-in/add-in STS in Visual Studio 2013 as there was for 2012
Thinktecture's EmbeddedSTS addin is oft-recommended and sounds cool, but *://EmbeddedSTS/ doesn't resolve(?? I don't get it). Also, binary links to their IdentityServer v2- are currently broken(?)
ADFS feature requires Windows Server 2012, a Domain, and self-signed certs - not too hard if you've done it before, but steep learning curve if you haven't.
ADFS requires SSL - Visual Studio 2013/IIS Express 8 easily supports SSL sites, just make sure the port number is in the range :44300-44398
ADFS manager Relying Party interface suggests examples referring to "sts" and "adfs/ls" and stuff which is, I think, misleading. Really they should just point back to your app (https://localhost:44300 for example). Although mine's not working right yet, so that could be related to my mistake.
Once you create a new Visual Studio Web Application project, there is no tooling to change the authentication mechanisms. Just start over with a new project and change the authentication to Organizational Accounts (for on-premises, as in my case). Your STS, such as your ADFS installation, has to be installed and reachable in order to complete this wizard.
Use the hosts file to override DNS for the VM's IP to the expected domain name if you're hacking together a test ADFS DC in a VM because you don't have rights to join a machine to the domain.
"Users are required to provide credentials each time the sign in" is helpful when working through sign-in sign-out problems at first.
I don't think any claims, even identity, are passed if you don't have any Claim Rules.
1) What is wrong such that my app still thinks the user is not authenticated?
I'm to the point where my https://localhost:44300/Default/Index/ action is supposed to display details of User.Identity (I also tried Thread.CurrentPrincipal.Identity) if the user is authenticated. I have a login Action link, generated with:
var signIn = new SignInRequestMessage(new Uri("https://dc.ad.dev.local/adfs/ls/"), "https://localhost:44300");
return new RedirectResult(signIn.WriteQueryString());
Clicking this link indeed takes me to the ADFS login page. Logging in brings me back to my application. Watching the preserved Network activity in Chrome Bug shows that I have a RequestSecurityTokenResponse message being posted back to the app, but the app's User.Identity is still not authenticated.
I have one Claim Rule configured: A "Transform an Incoming Claim" from "Windows Account Name" to "Name ID" as a "Transient Identifier". I see the <saml:NameIdentifier Format="urn:oasis:names:tc:SAML:2.0:nameid-format:transient">DevAD\jdoe</saml:NameIdentifier> represented in the sniffed POST. I've tried a bunch of other Claim Rules and still don't get authenticated.
I don't have any custom code for absorbing the claims. I am expect interception of a POST with the token to any app url to be converted to the User.Identity auto-magically by the framework, perhaps having been initiated by this wizard-generated code in Startup.Auth.cs:
app.UseActiveDirectoryFederationServicesBearerAuthentication(
new ActiveDirectoryFederationServicesBearerAuthenticationOptions
{
Audience = ConfigurationManager.AppSettings["ida:Audience"],
MetadataEndpoint = ConfigurationManager.AppSettings["ida:AdfsMetadataEndpoint"]
});
But part of me doubts this expectation. Is it correct? Is there a special known route that MVC WIF creates for accepting such login posts that I should be using besides my default route url?
2) How can I log out successfully?
I also have a logout action:
WSFederationAuthenticationModule.FederatedSignOut(new Uri("https://dc.ad.dev.local/adfs/ls/"), new Uri(Url.Action("Index", null, null, Request.Url.Scheme)));
But on this https://dc.ad.dev.local/adfs/ls?wa=wsignout1.0&wreply=https%3a%2f%2flocalhost%3a44300%2f page, "An error occurred". Event Viewer shows #364: "Encountered error during federation passive request."

And by the way, the following is what is supposed to be passively posted to the app, right? And, again, it is absorbed automatically?

===============
Below are the Claims defined. As suggested by #nzpcmad, the second one now "Send LDAP Attributes as Claims" from "Active Directory" to send "SAM-Account-Name" as "Name", "Display Name" as "Given Name", and "User-Principal-Name" as "UPN". And though the application receives the claims in the passive post, User.Identity.IsAuthenticated is still false and the other User.Identity data are blank too.
Pretty much right with your observations.
Just to note:
ADFS runs on Server 2008 R2, 2012 and 2012 R2.
Have a look at Use the On-Premises Organizational Authentication Option (ADFS) With ASP.NET in Visual Studio 2013.
It describes exactly what you are trying to do.
In particular, have a look at the claims.
You'll see it uses "Send LDAP Attribute" rather than the Transform you use.
I came across the same sign-out issue and it seems to occur if you do not have the issuing certificate in the trusted people certificate store.
What I am doing is I set both alfresco and share to session time out time 60 minutes in their web.xml file.
My scenario is
When I want to start a workflow in Start Workflow page, I fill all
necessary data but do not click "Start Workflow" button.
After session time out, I click this "Start Workflow" button.
At the first time, authentication box opens and request for username
and password.
I filled user name and password of another user.
It starts a workflow with the authenticated another user.
Other times for session timeout, it does not request authentication
box, but acts for previously requested authenticated user.
So I think Why does it happen??? Is it because of cookie??
Currently there are four cookies used, namely alfLogin, alfUsername2, JSSESSIONID, _alfTest. Only when user is logged out, alfUsername2 cookie is deleted and others are remained.alfLogin and alfUsername2 cookies' expire time is 7 days and other cookie are depends on session.
Can alfresco web script still be used after session timeout? If so, how can I avoid this condition?
Although I have to answer my own question, I just want to share my result. I have to trace much. But answer is so simple.
Firstly, it is not because of cookie.
This answer is not only just for clicking "Start Workflow" button but also calling alfresco webscript after session time out in share.
All calling to alfresco webscript is done by EndPointProxyController specifically org.springframework.extensions.webscripts.servlet.mvc.EndPointProxyController in spring-webscripts-1.0.0-sources.jar.
In handleRequestInternal method if there is no session and basicHttpAuthChallenge is true, basic authentication box is shown as below.
else if (this.basicHttpAuthChallenge || descriptor.getBasicAuth())
{
// check for HTTP authorisation request (i.e. RSS feeds, direct links etc.)
String authorization = req.getHeader("Authorization");
if (authorization == null || authorization.length() == 0)
{
res.setStatus(HttpServletResponse.SC_UNAUTHORIZED,
"No USER_ID found in session and requested endpoint requires authentication.");
res.setHeader("WWW-Authenticate", "Basic realm=\"Alfresco\"");
// no further processing as authentication is required but not provided
// the browser will now prompt the user for appropriate credentials
return null;
}
else
{
// other coding
}
We can avoid this condition as
in endpointController of slingshot-application-context.xml, change
basicHttpAuthChallenge to false.
Like
<!-- Override EndPointProxyController to enable Basic HTTP auth challenge on 401 response -->
<bean id="endpointController" class="org.springframework.extensions.webscripts.servlet.mvc.EndPointProxyController">
<property name="cacheSeconds" value="-1" />
<property name="useExpiresHeader"><value>true</value></property>
<property name="useCacheControlHeader"><value>true</value></property>
<property name="configService" ref="web.config" />
<property name="connectorService" ref="connector.service" />
<property name="supportedMethods"><null/></property>
<property name="basicHttpAuthChallenge"><value>false</value></property>
</bean>
I'm using Spring Security 3 and my ApplicationContext-Security.xml specifies
<form-login login-page="/genesis" default-target-url="/diagnostics/start-diagnostics"
authentication-failure-url="/genesis?authfailed=true"
authentication-success-handler-ref="customTargetUrlResolver"/>
<access-denied-handler error-page="/genesis?notauthorized=true"/>
<logout logout-success-url="/genesis"/>
<session-management session-authentication-error-url="/genesis">
<concurrency-control max-sessions="1"/>
</session-management>
However when I log into my app in a second browser, then return to my first browser as soon as I try to do anything I get a plain white screen with the message "This session has been expired (possibly due to multiple concurrent logins being attempted as the same user"
How do I configure Spring Security 3 to display my own "you've been disconnected" URL?
You can either:
force concurrency filter to throw authentication exception (and it'll be handled by <form-login>),
provide your own session-expired page.
These situations are described here in Spring Security manual:
<concurrency-control> Attributes
error-if-maximum-exceeded
If set to "true" a SessionAuthenticationException will be raised when
a user attempts to exceed the maximum allowed number of sessions. The
default behaviour is to expire the original session.
expired-url
The URL a user will be redirected to if they attempt to use a session
which has been "expired" by the concurrent session controller because
the user has exceeded the number of allowed sessions and has logged in
again elsewhere. Should be set unless exception-if-maximum-exceeded is
set. If no value is supplied, an expiry message will just be written
directly back to the response.
Also check ConcurrentSessionFilter and ConcurrentSessionControlStrategy for more details.
Answering your question: in your config you should have something like this:
<session-management session-authentication-error-url="/genesis">
<concurrency-control max-sessions="1" expired-url="/sessionExpired.jsp" />
</session-management>
Note that expired-url is not the same as session-authentication-error-url.
