Hi folks,

I'm using JMeter to stress test an API. I've got Basic Authentication set up - seems to be working great.

Now, i'm trying to randomize the credentials that JMeter passes across the wire. So, there's two ways I know I can do this.

  1. Add a custom HTTP Header (via an HTTP Header Manager Element) and set then value to the random fields (ie. something I've read in from a csv file)
  2. Use the HTTP Authorization Manager Element and pass in the username and password there.

Now, if I try and use method (1) above, I need to create the following header/data :-

Authorization: Basic <some Base64 encoded string in the format username:password>

eg.
Authorization: Basic OnVzZXIxOnBhc3Mx

Kewl. simple. BUT that header value is not getting passed across the wire :( I can add any other header type and it's passed across the wire..

hmm .. ok then .. lets try method (2).

Now that works .. but I can only hardcode in the username & password. I can't see how I can pass in a username VARIABLE (ie. ${usernmae} ) or a password VARIABLE (ie. ${password} ).... If it's hardcoded, then the server correctly replies with the correct page/data.

so .. can someone please help?
