How to Login LDAP with Jmeter? - authentication

I am currently recording a web with Login LDAP that means I need to input username and password in popup authentication (screenshot attached).
After I am done recording, I play back the script, and it always failed.
And I followed tutorial from https://www.blazemeter.com/blog/windows-authentication-apache-jmeter but it still failed.
Here is my Test Plan:
Here is HTTP Authorization Manager setting:
Please help.
Thanks,
Rio

If you really "followed the tutorial" you should know what is your authentication type challenge, the choice is in:
Basic Access
NTLM
Kerberos
Your setup is wrong for any of the types as you should have either base url or domain or domain+realm+appropriate configuration in jaas.conf and krb5.conf files.
I don't think sending one request is sufficient for simulating log in process, real users do the following:
open login page (at least 1 request)
type credentials (you need to mimic the time required to type using Timers)
perform login (another at least 2 request)
You may also need to perform correlation of dynamic parameters (if any), check out How to Handle Correlation in JMeter to learn more about the concept / implementation
Your approach of AJAX requests simulation is wrong, as per the definition AJAX requests are Asynchronous, to wit real browsers execute them at the same time while in your setup they are sequential. So consider placing the AJAX calls under the Parallel Controller

Workaround in JMeter for Autorization Bearer from Microsoft login (for single page application with specific organizational service accounts)

Single page application with specific organizational service accounts uses microsoft authorization (2.0).
To pretend in JMeter as user working with this application, it is enough to have Bearer access_token and then pass this Bearer in header of JMeter script requests.
I can manually login with user credentials in browser, get Bearer and set up it as variable in JMeter in API requests headers and successfully continue to work with application functionality.
Also I can login in WebDriverSampler (and I suppose, can emulate with WebDriverSampler another user's actions with application like in "browser").
What is the simplest and shortest way, having all above, to get Bearer somehow for API calls in a script without time-consuming or programming-oriented complex solutions? Is it possible somehow to use WebDriverSampler requests for parsing Bearer?
On this stage, the goal is to collect (and generate) Bearers, which have long time of life, with intention to use this set of Bearers for multi-session JMeter "users" later. (Because users amount is under cost constrtaints with users service accounts, i.e. I have 1 provided user only).
Will be very appreciated for grace tips and advices with such kind of problem.
It should be possible to use i.e. BrowserMob Proxy for capturing the traffic between the browser orchestrated by the WebDriver Sampler and the backend, this way you will be able to extract Authorization header value and i.e. store it into a CSV file for later re-use.
In general it should also be possible to replicate the browser's authentication flow with JMeter's HTTP Request samplers as browsers don't do any magic, they just send HTTP Requests and display the responses so well-behaved JMeter test should generate the same network footprint as the real browser does

Jmeter is not passing the Microsoft authentication in my script for testing performance on my test website, showing Access denied

My application has a microsoft authentication on it before logging into it & I have recorded script but when I am running it, it is showing me access denied error everytime.I have set authentication manager but still same error. See image attached.
I have tried HTTP Authentication Manager & provided login username & password.
Most probably your application uses OAuth therefore it is neither something you can really record and replay nor handle with the HTTP Authorization Manager.
Depending on your application setup you will either need:
To perform correlation of the query parameters
Or to pass the relevant Authorization Bearer token via HTTP Header Manager. The process of obtaining the token can be different depending on your application login chain implementation, check out How to Run Performance Tests on OAuth Secured Apps with JMeter article to get a couple of ideas regarding bypassing 3rd-party provider login challenge in JMeter tests.
Check if you can provide the auth credentials as parameter of the requests.
for example www.abc.com?username=abc&password=abc. Replicate the same with Jmeter
Use Fiddler (or you can get away with browser dev tools if you don't mind searching manually) and log in manually via your browser.
Check the request(s) that are submitted to Microsoft for tokens/GUIDs and search for where the browser got those strings from (it'll be in one of the previous requests' responses' bodies or redirect URLs. In Fiddler you can use the find function on responses, browser dev tools you'll have to find it manually).
You can then use a JMeter Regular Expression Extractor post-processor (or any of the other post processors you prefer) to extract that string from the earlier request into a variable.
In your login request you can then use the value of that variable (if you used regular expression post-processor with a capture group the first group's value will be ${variable_g1}
You'll probably have an anti-forgery value that you can extract from the HTML of the login page which needs to be submitted with the username and password and then in the response you'll get a cookie set and potentially JWT token in the response body/URL.

How to work with apache Jmeter for login applications?

Hi I would like to test using Jmeter for my application which has login page. I am able to write Sample http request for login page which is working ( passing username and password as POST parameters).
But the another Sample HttpRequest (home.do) is not working which is again redirecting to login page. I also added HttpCookieManager at Thread level. Not sure why the authentication is not carry forward to other pages, Can anyone please help me on this.
Most probably your test doesn't work due to missing or incorrect correlation. The absolute majority of modern web applications use dynamic parameters for different reasons (client state tracking, security, etc.) so you need to setup your test plan like:
Open Login Page (usually GET request)
Extract dynamic parameters
Perform Login (usually POST request), provide credentials and dynamic parameters extracted from the previous request
Extract dynamic parameters
Open Home Page (usually GET request)
etc.
You can extract dynamic parameters using JMeter Post-Processors
Also make sure you add HTTP Cookie Manager to your Test Plan to represent browser cookies and deal with cookie based authentication.
BTW, you can quickly build test plan "skeleton" by simply recording your test scenario using HTTP(S) Test Script Recorder

JMeter's ResourceLastAccessedTime GET request failed

I am trying to use JMeter to test our Web Application. We originally used LoadComplete to test our Web Application, but because LoadComplete is not able to run on a non-GUI mode, we were not able to use the max stat’s from our test server (strain our 8 CPU’s and 8GB’s of RAM). That is why I moving towards JMeter (https://blazemeter.com/blog/5-ways-launch-jmeter-test-without-using-jmeter-gui).
The test includes logging in, choosing a specific app, do a simple task through this app and then end the recording. The HTTP Requests, which are failing are printing Failed Access on their Response Data on the View Results Tree.
I used the HTTP(S) Test Script Recorder to record each HTTP request. My JMeter project is failing on a few different HTTP Requests, which includes oauthtoken Get Request that includes jessionid="item", a GET resourceLastAccessedTime Request, and a couple GET resourceLastAccessedTime Requests. I tried to follow blazementer's guidance for how to use JMeter for Login Authentication, because these requests seem to be involved with the authentication of each user after logging in and the problem I am getting on Response data for each of these requests on the View Results Tree it says Access denied. (https://docs.blazemeter.com/customer/portal/articles/1743663-how-to-use-jmeter-for-login-authentication-).
One of the steps is to "copy and paste" the Parameters from the Post request after you login to these requests. I can add these parameters to these requests right below where it says Send Parameters with the request, but our POST request only has two parameters (the login name and the password). Is there somewhere else to look for these parameters?
I tried a combination of a lot of different attempts, but I am still unsuccessful (meaning: I moved the Regular Expression Extractor to a few different HTTP requests and I moved which HTTP requests to put those parameters and I have not been successful yet).
Do you know of a URL that could be helpful for this?
Don't trust Test Script Recorder! It doesn't follow any logic while recording your requests. It just records requests processed through proxy as they are. In case you use parameters that can't be defined as constants, the best way would be to rewrite the script manually.
Be patient and spend some hours (only once!) to learn how to construct any test scenarios (even complex) manually using Jmeter GUI. It will save you a lot of time for debugging.
It seems like (just a guess) that your test scenario doesn't contain Cookie Manager item. Based on what you wrote above, it seems like after logging to serer (by sending POST with login and password) it sets some cookies by Set-Cookie HTTP header. These cookies should be included in every next request as a prove that you successfully logged in before (the most common logic for simple web applications). So, if you get Access Denied, means you didn't include appropriate cookies in test request. Use Cookie Manager for that.
Feel free to ping me in case you need any assistance.
Jmeter help manual is all you need to know about how each element works.
P.S.: Jmeter also can generate distributed load from multiple slave servers, in GUI and CLI modes both. So, in case you need to stress your server yout, Jmeter is the best choise.
And welcome to Jmeter users family! Good luck.

CAS authentication and limiting access for specified users

I'm using CAS (Central Authentication Service) from Jasig in a client JSF app running on tomcat 6 server. I would like to limit the access to the app just for the users specified in my database rather than all the users which can be authenticated using that CAS service. When the user attempts to log in, I need to check if his username is also in my database's table user and if it is - allow the access to the app. Otherwise, I would like to redirect user to a page "You don't have permission to access this part of the application". So I need authorization as well. Is there a good way to authorize the users in jsf 2.0? Thanks in advance for any help/suggestions.
Sounds like you need to design a custom Authentication Handler class in CAS. In theory, your handler would extend this [1], perform all the necessary checks and database look ups and will then be able to return a signal that indicates whether or not the user could authN.
You should then reference your custom handler in the deploerConfigContext.xml file.
For displaying the message, you could either throw an exception with the proper messages code, such that the message would appear above the login form, or you could alter the spring webflow and generate a new view-state which the user would be redirected to, if they fail to get access. The first approach is much easier to implement.
Another approach would be to take advantage of the isUserInRole() method [2] using the persondir api.
