How to deal with 401 Unauthorized response i Jmeter V3.0 or lower?

Question

I am trying to login the-internet.herokuapp.com/basic_auth using admin:admin as credentials.

I am using Jmeter v3.0 and I added HTTP Authorization manager, Cookie manager and also added the name and value in header manager as shown in the image, but I am still getting 401 unauthorized response.

I tried the same thing in a different system with Jmeter v3.1 and its working.

Does anyone know how to resolve issue with Jmeter v3.0 or lower?

I cannot reproduce your problem using JMeter 3.0 and only having HTTP Authorization Manager added apart from the HTTP Request:

I would recommend removing your Authorization header from the HTTP Header Manager just in case.

See How to Use HTTP Basic Authentication in JMeter article for more details on bypassing basic access authentication in JMeter tests.

It is hightly recommended to use the latest JMeter versions where possible as newer versions normally come with bug fixes, performance improvements and brand new features so consider upgrading to JMeter 3.2 (or whatever is the latest version available at the JMeter Downloads page)
