How can we achieve NTLM authentication using Jmeter Automation - jmeter

I was previously used Visual studio web test for automation. Now we have moved to Jmeter. We are trying to solve NTLM Authentication issues here but are unable to find out where to pass Credentials. The parameters below are required for file authentication in VS webtest:
CredentialUserName="CredentialUserName"
CredentialPassword="CredentialPassword"
PreAuthenticate="True"
I have found some helpful links and understand how NTLM works but am unable to find out how to use them in Jmeter.

JMeter provides HTTP Authorization Manager which deals with Basic, NTML and Kerberos authentication types, just add it to your Test Plan and provide username, password and domain there, JMeter will automatically build the relevant Authorization header and add it to your request(s).
See Windows Authentication with Apache JMeter article for more information.

How to handle redirection when login Jmeter

I am doing performance testing. I have a URL abc.com it redirects to http://github.com for login. Because abc.com is registered in Github. What will be the approach to login into the application with Jmeter
It's called OAuth and you need to implement the required authorization flow, most probably Authorization Code Grant, however it depends on how your "abc.com" is exactly integrated with Github.
All the information on possible options and flows is listed on Github website so you either need to ask around what exact flow is being used or inspect the traffic from your browser using your browser developer tools or external sniffer tool like Fiddler or https://www.wireshark.org/
Actually it's only matter of passing correct parameters to Github https://github.com/login/oauth/authorize and https://github.com/login/oauth/access_token endpoints and correlating the dynamic values using suitable JMeter Post-Processors.

Executing Login API in which Authentication process happens with Active Directory

I am trying to do the performance testing of a logistics application. 2 types of users are there - Internal users & External Users. For internal users the authentication process happens normally; usual database. I was successful in executing the jmx script for Internal users. But for External users, the authentication process happens with Active Directory. In this case when i tried to execute the jmx script, the user is not getting logged in to the application. But the login api doesn't gives any error, the Response Code is 200 but in Response I'm getting the message "Try again". Do we need to do any additional settings in Jmeter for Active Directory Authentication? Can anybody help me in this?
For "internal" users you might need to add HTTP Authorization Manager and configure not only username and password but also domain, realm and use appropriate mechanism for NTLM or Kerberos
See Windows Authentication with Apache JMeter article for more detailed explanation and example configurations
You may be missing out on a few key things such as HTTP Headers or some additional data that needs to be sent with the request.
To resolve this. you can analyze the request in the developer tools of your browser and then generate the same headers with the request. This will resolve the issue.

Not able to capture request response for CRM Dynamics 365 app using Jmeter

While system proxy is set with Jmeter, CRM Dynamics 365 app is prompting for credentials repeatedly until it gives "HTTP 401.1 - Unauthorized: Access is denied" error at last. Without the proxy, users can access the CRM application at ease over browsers. Following steps are already taken, but no luck yet.
Jmeter root certificate is installed
Domain admin credentials are used for login
For authentication, NTLM service provider is set at IIS
Any help is appreciated!
In recorder advanced tab , switch Http request implementation to Java and try again.
If it doesn’t work, investigate wether it’s ntlm or keeberos.
Alternatively you can start authenticating without proxy setuo and once done, you switch browser to use jmeter proxy.
You can record test cases over BlazeMeter then import them into JMeter. That is worked for me.

JMeter authentication error : 401

Currently I am having problem to login my application using Jmeter scripts for SSO login.Shows unauthorized but all my credentials that I provided to login into application are okay.
It was working earlier.
I have already implemented each and everything that require to run Jmeter to my application earlier.
Currently I am stuck at this point.If anyone has idea? If so it would be so nice to have that idea/help.
check if it is NTLM authentication then you need to provide Mechanism as "Basic Digest" and if any domain then mention in Realm as "{domainname}\"
Most probably this is due to irrelevant configuration of the HTTP Authorization Manager
Looking into WWW-Authenticate Negotiate, it seems application you are testing is using NTLM or Kerberos authentication so you need to properly configure JMeter in order to be able to bypass it.
See Windows Authentication with Apache JMeter article for more detailed explanation and example configurations for NTLM and Kerberos.

"Authorization has been denied for this request" in jmeter

I am trying to perform load testing using JMeter on my project's web service (search web service for instance), the problem I am facing is that I am getting {"Message":"Authorization has been denied for this request."} in "Response data" tab in JMeter
This same message I also get when I try to paste the same query string (which I am using in JMeter as Path) in browser new tab without logging in first,, but if I login on my project first and then try to paste the query string in browser's new tab then it works fine.
Now the actual problem that I am facing in JMeter is that I am unable to log in to the system using "HTTP Header Manager"
I tried by adding Basic authentication in "HTTP Header Manager" but it didn't worked, then my developer told me that he is using "ASP Membership" authentication instead of Basic authentication,, now I am not sure how to use this type of authentication in JMeter.
I think I have explained my problem in detail here, can any one please help me in this as I am really stuck into it.
Thanks in advance
You need to add a cookie-manager to your Thread Group. This will preserve the cookies ( hence sessions) between requests. Next add a http request which will do a POST of your login form then another HTTP Request with your actual request. This way you are imitating the steps you do on your browser - that is - login followed by request.
Looking into ASP.NET Forms Authentication Overview article:
Forms authentication lets you authenticate users by using your own code and then maintain an authentication token in a cookie or in the page URL.
So depending on implenentation of ASP.NET Forms on server side you can use one of the following test elements:
HTTP Cookie Manager
HTTP URL Re-writing Modifier
Also you may need to perform the correlation of the mandatory dynamic parameters such as VIEWSTATE or EVENTVALIDATION. See ASP.NET Login Testing with JMeter guide for detailed explanation and walkthrough.
