Acceptable Usage policy issue with delegate authentication - java

We have configured both features stated in the title based on the official docs(aup & delegate authentication.
We use delagate authentication to intergrate with an external saml idp provider. So we have two means of authentication. The idp authentication and the local one(cas internal database authenticator).
After external and internal authentication we need to show the acceptance usage policy view when a condition A is met.
The above works as intended for local login, however, when authentication is performed in the external idp the acceptable usage policy page is not shown even if the condition A is met and the user eventually logs in the initially requested service.
Question: Why is this happening and are there any possible workarounds?
Cas server version: 5.3.7

If you examine this block, you will find that verification of policy usage is linked to and created as an entry action of the STATE_ID_CREATE_TICKET_GRANTING_TICKET:
final ActionState ticketCreateState = getState(flow, CasWebflowConstants.STATE_ID_CREATE_TICKET_GRANTING_TICKET, ActionState.class);
ticketCreateState.getEntryActionList().add(createEvaluateAction("acceptableUsagePolicyVerifyAction"));
createTransitionForState(ticketCreateState, AcceptableUsagePolicyVerifyAction.EVENT_ID_MUST_ACCEPT, VIEW_ID_ACCEPTABLE_USAGE_POLICY_VIEW);
This is a limitation of the AUP flow such that the result of the verify action is sort of ignored and it's not taken into account to trigger the final view, even if it indicates so, in the delegation use case specially.
The 6.0.x branch changes this logic a bit to improve this behavior:
val ticketCreateState = getState(flow, CasWebflowConstants.STATE_ID_CREATE_TICKET_GRANTING_TICKET, ActionState.class);
createEvaluateActionForExistingActionState(flow, ticketCreateState.getId(), AUP_VERIFY_ACTION);
createTransitionForState(ticketCreateState, CasWebflowConstants.TRANSITION_ID_AUP_MUST_ACCEPT, VIEW_ID_ACCEPTABLE_USAGE_POLICY_VIEW);
You're welcome to experiment with the same approach in your 5.3.x deployment and report back. Be sure to test both cases thoroughly. If things work as expected, please post back and you can then post a pull request to the project to change/fix this behavior.
PS Note that that the entanglement of various webflow actions and states is something very tricky, as there are many modules that wish to insert themselves into the right webflow state to accommodate some behavior. Such modules generally know nothing about each other, and attempt to augment the flow somewhat agnostically. In these situations, chaining such things together can quite tricky.

DocuSign AutoResponded RecipientEvent

I am building an envelope based webhook to receive status updates from DocuSign, rather than my current "polling" based method. I have the below code to create the RecipientEvent
RecipientEvent autoRespondedRecEvent = new RecipientEvent();
autoRespondedRecEvent.setRecipientEventStatusCode("AutoResponded");
recipientEvents.add(autoRespondedRecEvent);
I have similar RecipientEvents for Sent, Delivered, Completed, Declined, and AuthenticationFailed; however, all of these events work as intended, other than the 'AutoResponded' one.
Again, I am not using the account-level webhook, but the envelope based setup as have a fairly complex development/test environment. I have read another question on SO where the solution was a configuration setting
Return Recipient Auto Responded Status via Connect/Api
However, this solution does not apply in my case, as I'm not using an account-level webhook.
That's a back-end setting that should still apply through envelope-level webhooks. I'd recommend opening a support case to have Return Recipient Auto Responded Status in Connect/API enabled for your account.
I'd recommend providing both your Demo and Production account IDs when you do so.

Correct way to handle a REST API path that can be called synchronously or asynchronously

I'm working on a Spring Boot REST API that handles document and can launch a check on a document.
I have a document resource: /doc:
Create a doc with POST /doc
Rest of the CRUD actions with /doc/{id}
Now I can launch a check on a doc, check can be seen either as an action or as a sub-resource.
It's pretty straightforward to launch (create) a check on a document: POST /doc/{id}/check
The check can however take some time so I want to give the user the choice to launch a synchronous or asynchronous check.
How would I handle this path wise?
Should the user choose sync or async check through a query parameter on POST /doc/{id}/check?
Should I create 2 separate paths?
Also in the case of an async check, I would create a temporary Task resource that can be pooled to know the status of the check.
But then if both check and task are returned from the same path it gets confusing, no?
I read an article that says the resource returned in async should be a check resource filled as much as possible but with a link to the task that can be pooled.
That seems like a good way; I would return a partial check if async with a link to the /task/{id} associated with the check.
However I'm still confused as to what path my API should offer to let the user pick between sync and async checks.
How would you handle it path and resource wise?
Basically it's up to you. Usually if it's a big chunk of data you want to query like /resource/{id} most APIs I have used use GET for synchronous requests and POST for async request returning task or job ID.
For POST in your case if the creation/checking takes time I would consider always doing it asynchronous and returning HTTP 202 Accepted and doc/{id}/check/{id} url where the user can see the result if it is ready or some status that it is still working.
If you want to give them a choice to wait or not it's up to you how to do it. There is a standard header that can be used to modify behavior. For example Expect: 202-accepted for async calls and no header or Expect: 201-created for synchronous calls. This makes the API a bit less clear even though it is a standard. Most people (including me) would probably stick to adding a parameter to the URL for clarification. I don't think it should be in the POST data because it should be data related to the object you are creating
There are multiple questions here. I would try to answer one by one
Checking the health of a resource can be done with query param
/doc/{id} - GET Get the resource details
/doc/{id}?healthCheck=true&async=true GET - Get the resource details and trigger an async health check
For the async health check the response as you mentioned will be 202 and the response contains the link to the health status URL
HTTP/1.1 202 Accepted
Location: /doc/12345/status
If the client sends a GET request to this endpoint, the response should contain the current status of the request. Optionally, it could also include an estimated time to completion or a link to cancel the operation.

Why does weblogic's "not found" behavior change after the first attempt?

I'm using Weblogic 10.3.5. I work on a large legacy enterprise application with Struts (1.x) mapped as the default servlet.
Background
A bit of legacy convolution to start: each enterprise customer has a "subscriber ID" which their users must provide at login in addition to their username and password. Subscriber IDs are numeric and always at least four digits, usually five. If you go to mysite.com/, you are presented with a three-field login page: subscriber ID, username, and password.
Our largest enterprise customers didn't like that, so many years ago we introduced skinned login pages: go to mysite.com/12345, where 12345 is your subscriber ID. We'll prepopulate and hide the subscriber ID field, and skin the login page with the enterprise customer's logo and color scheme.
Years later, we had 100+ servlet mappings, one for each subscriber. Every new customer required a software deployment to add the servlet mapping, so our implementations team was hamstrung by the dev team's deployment schedule, which in turn was limited by our large enterprise customers' need to budget time for user acceptance testing.
To address that, we changed the URL: mysite.com/login/12345, where /login/* is mapped to a single servlet that accepts any subscriber ID. We kept the old servlet mappings around so that existing customers didn't have to change the URL, but that left two annoyances:
A few hundred lines of cruft in web.xml
As a developer or QA, it's annoying to have to know whether this is an old subscriber or a new one before you know what URL to use to log in. Try to use the old method for a new subscriber? You get a 404 page.
Here's what I did
We had a pre-existing custom 404 page, correctly defined in web.xml and behaving exactly as expected. I updated it with the following code, right at the top:
<%
if (request.getRequestURI().matches("^/[\\d]{4,}$")) {
// probably someone trying to log in with the old-style URL
response.sendRedirect(String.format("/login%s", request.getRequestURI()));
return;
}
%>
This worked like a charm, until I noticed one oddity:
Here's what's wrong
The very first time I try to visit a URL that should result in a 404 but will be redirected because it matches the regex, it doesn't redirect. With my debugger, I've determined that the reason is that request.getRequestURI() returns "/errors/404error.jsp" rather than "/12345" like I would expect, resulting in the regex not matching and our normal 404 page being served to the user.
My first thought was that something was telling the browser to redirect to the 404 page, but Chrome Dev Tools "Network" tab indicates that is not the case.
After it fails that first time, my change works every subsequent time until the application server restarts.
If I hit /login/12345 first it loads fine. Any subsequent attempt to hit /12345 will work fine, so it seems like it might have something to do with the login servlet not being fully initialized until after the first request. Weblogic is closed source, so I'm not able to dig into what's happening.
Here's my question
I know it's a pretty weird thing I'm doing; I'm open to other approaches. But the question is this: what's causing the different request URI on the first attempt, and how do I fix it? I've scoured the HttpServletRequest object in the debugger and I don't see any indication of the real request URI.

WebSphere Commerce - How does ReLogonFormView / Session Expiration Work?

Sorry for the broad topic. Basically, WSC is supposed to have out-of-the-box session timeout handling by forwarding the user to the ReLogonFormView, which the user can presumably configure (through Struts) to any jsp that they choose. We use a custom logoff command, and it seems to be affecting that view showing up.
I'm not looking for a specific solution to this problem, I'm just looking for general knowledge about how WSC (v6) handles session timeouts (how it determines that the session has timed out) and what command(s) it runs by default when / if / to determine the session has expired.
This is my current knowledge on this subject...
The session timeout is a global value for all web modules and can be found in the wc-server.xml and is set to 30 minutes OOTB.
When a timout occurs, the OOTB LogoffCmd would normally be called, which will set up the necessary URLs to navigate to the ReLogonFormView URL while keeping hold of the URL where the session timeout occurred.
If the ReLogonFormView contains userid/password fields to allow the user to logon again, the user will then be redirected back to the page they were originally on.
More info can be found in IBM InfoCenter under "LoginTimeout".
If you extend the OOTB LogonCmdImpl, you should not try and set the forwarding URL, or that will interfere with the OOTB navigation.
I think you should perform your custom logoff functionality and then call super.performExecute() to allow the OOTB navigation logic to take over.
Note: You can retrieve the URL you were originally on via a call to getReferrerURL() and the ReLogonFormView should be returned from getURL().

Session management between thick client and server?

My application is a Eclipse Rich Client and I would like to add authentication and authorization features to. My Users and roles are stored in a database and my application also has a web based admin console which lets me manage users and roles. I am leveraging Spring security on this admin console.
So here's my requirement:
I would like my thick client to provide users with a login dialog box. The authentication would need to be performed on the server side (it could be a webservice) and the roles have to flow in to the thick client. I would also like to manage sessions on the server side, somehow.
I really can't think of any easy way to doing this. I know that if I were to use Spring Rich Client, it would integrate pretty well with Spring Security on the server side.
But, that is not an option for me at this point.
Please share your thoughts on how to acheive this. Appreciate your help.
Since you're leaning toward web services (it sounds like you are) I'd think about taking the user information from your rich client (I assume user ID and password), using WS-Security to send the encrypted info to a web service, and having the web service do the auth stuff. Also I'd think about the web service returning any info that you want to go back to the rich client about the user (first/last name, etc).
I developed a similar application recently using the Challenge-Response-authentication. Basically you have three methods in your webservice or on your server
getChallenge(username) : challenge
getSession(username, response) : key
getData(username, action?) : data
getChallenge returns a value (some random value or a timestamp for instance) that the client hashes with his/hers password and sends back to getSession. The server stores the username and the challenge in a map for instance.
In getSession the server calculates the same hash and compares against the response from the client. If correct, a session key is generated, stored, and sent to the client encrypted with the users password. Now every call to getData could encrypt the data with the session key, and since the client is already validated in getSession, s/he doesn't have to "login" again.
The good thing about this is that the password is never sent in plain text, and if someone is listening, since the password is hashed with a random value, the call to getSession will be hard to fake (by replaying a call for instance). Since the key from getSession is sent encrypted with the users password, a perpetrator would have to know the password to decipher it. And last, you only have to validate a user once, since the call to getData would encipher the data with the users session key and then wouldn't have to "care" anymore.
I've a similar requirement I think. In our case:
user provides username and password at login
check this against a USER table (password not in plain text btw)
if valid, we want a session to last, say, 20 minutes; we don't want to check username and password every time the thick client does a retrieve-data or store-data (we could do that, and in fact it wouldn't be the end of the world, but it's an extra DB op that's unnecessary)
In our case we have many privileges to consider, not just a boolean "has or has not got access". What I am thinking of doing is generating a globally unique session token/key (e.g. a java.util.UUID) that the thick client retains in a local ThickClientSession object of some sort.
Every time the thick client initiates an operation, e.g. calls getLatestDataFromServer(), this session key gets passed to the server.
The app server (e.g. a Java webapp running under Tomcat) is essentially stateless, except for the record of this session key. If I log in at 10am, then the app server records the session key as being valid until 10:20am. If I request data at 10:05am, the session key validity extends to 10:25am. The various privilege levels accompanying the session are held in state as well. This could be done via a simple Map collection keyed on the UUID.
As to how to make these calls: I recommend Spring HTTP Invoker. It's great. You don't need a full blown Spring Rich Client infrastructure, it can be very readily integrated into any Java client technology; I'm using Swing to do so for example. This can be combined with SSL for security purposes.
Anyway that's roughly how I plan to tackle it. Hope this is of some use!
Perhaps this will help you out:
http://prajapatinilesh.wordpress.com/2009/01/14/manually-set-php-session-timeout-php-session/
Notice especially this (for forcing garbage collection):
ini_set(’session.gc_maxlifetime’,30);
ini_set(’session.gc_probability’,1);
ini_set(’session.gc_divisor’,1);
There is also another variable called session.cookie_lifetime which you may have to alter as well.
IIRC, there are at least 2, possibly more, variables that you have to set. I can't remember for the life of me what they were, but I do remember there was more than 1.
