Hey Felix,
thanks for the help so far :)
BTW, does it make a difference that I am working from a 64b Linux box?
Although when within the domain, on a windows (citrix) box I get the
same
errors.
I do my testing from linux, so I am sure, that linux works.
I started off initially trying it over 88, which gives the exact same
time-out.
Then maybe not only the port is wrong, but the dns name also? The kdc is
not the website server you are trying to connect to, but the key
distribution center, that is the kerberos server.
When I asked the implementation partner they claimed it should just run
over 443, but than again, what do they know :)
If they tell you it is 443, they probably mean the webserver, which is
most likely not the kdc.
One thing I have noticed so far, is that the request headers contain
nothing towards auth types:
That is OK, since you have no TGT or service ticket and if it is the
first request no knowlegde, that the server is willing to speak SPNEGO.
Request Headers:

Also, Tried connecting straight through Java and that worked like a
charm.
Code is somewhat like this:
public class NTLM_ping {
public NTLM_ping(){
super();
}
public static void main(String[]args) throws Exception {
DefaultHttpClient httpClient = new DefaultHttpClient();
httpClient.getAuthSchemes().register("ntlm",new
NTLMSchemeFactory());
That is great, but you are not using kerberos here.
This is NTLM, which you could use with jmeter, too. I believe you have
to fill in the domain and
realm columns and use BASIC_DIGEST instead of Kerberos.
But keep in mind, that kerberos is cooler and probably more secure.
// add credentials
httpClient.getCredentialsProvider().setCredentials(
new AuthScope("TEST", -1),
new
NTCredentials("m.devrieze","PassWord","tst-crm20.test.nl
","TEST"));
HttpGet httpGet = new HttpGet("http://tst-crm20.test.nl";);
// ignore cookies
/*httpGet.getParams().setParameter("http.protocol.cookie-policy",
CookiePolicy.ACCEPT_ALL);
*/
try{
// execute the GET
HttpResponse status = httpClient.execute(httpGet);
System.out.println(status.getProtocolVersion());
System.out.println(status.getStatusLine().getStatusCode());
System.out.println(status.getStatusLine().getReasonPhrase());
System.out.println(status.getStatusLine().toString());
}finally {
// release any sources
}
And by the way, could you stop answering in top-post style?

That is probably because you don't connect to the right port and noone
responds to you. Try another kdc port.

I have been struggling somewhat with JMeter and kerberos lately.
Google
so
far has not been able to help me out with the issue I am facing.
The system under test is a Microsoft CRM 2013 platform, up until a
few
days
ago my tests worked fine since basic auth was switched on. However
on
the
most recent drop with changes they also switched over to kerberos
auth
only.
I have:
* filled in the KRB5.CONF with all relevant information
* HTTP AUTH Manager in the script with base URL, username,
password,
domain and KERBEROS filled in
* HTTP Request defaults to ensure and enforce HTTP4 use, HTTPS over
port
443 and the same base URL all over the place
However I cannot get it to work properly, logging in simply refuses
to
work
for me. I'd really appreciate some help here, I use Jmeter fairly
often,
with this I am however completely stuck.
When running the first step, which instantly receives the KERBEROS
ath
request I get the following in my logs:

It seems, that the kerberos server did not answer the request for
a
service ticket (at least not within the default timeout of 30s).
Could you rerun the test with the java system property
"sun.security.krb5.debug" set to true?
Could you post the contents of your krb5.conf and jaas.conf file?

Felix
