The response code is 302, response message is "moved temporarily", response
contents (after reading the inputstream) is empty. Basically, nothing comes
back. Should I find anything in the logs to indicate that my posts are infact
making their way to CAS?

302 is not an error. 302 is the HTTP status code for "Moved Temporarily" (i.e.
a redirect). It means that CAS sent you a request to do a redirect to a
particular url (in this case your service url with the attached service
ticket). You should read the response sent back and parse out the ticket.
The HttpUrlConnection class should have methods to retrieve the response.

Ok, I goofed. It actually says error 302.
I am using httpurlconnection class.
newurl = new URL( "
http://localhost:8080/cas/login?username=aaa&password=aaa&service=http://localhost:8080/somestuff/<="+lt);
Is the above format correct? I mean, the username, password, service and lt are
all set correctly?
I think something is wrong in the way I am passing the params.

What is doing the infinite redirect? Your browser or whatever you are using to
the do the GET/POST? If you're not following redirects there is should be no
way it can redirect. It should stop.

I did set it to not follow redirects with the same results. Just to confirm, I
need to do a GET and a POST to the SAME url (/login), correct?
Any other suggestions highly appreaciated...
Thanks.

You may want to set whatever it is you are using to retrieve the login page to
not follow redirects.

Hi,
I tried your instructions and got as far as post to login again. I posted to
http://localhost:8080/cas/login?username=dummy&password=dummy&service=http://localhost:8080/index.html<="+lt
The last lt is actually a string containing the value of 'lt'. I get back a
"server was redirected too many times" error. I am using
http://localhost:8080/index.html for service since I don't really have a
service to refer to. I tried http://www.yahoo.com just to check it out with no
success.
What am I missing?
Thanks.

You can do a GET/POST and parse the response. You would need to do the
following:
1. Do a GET call to /cas/login
2. Parse the return page for the "lt" value
3. Do a POST call to /cas/login with the username, password, service and lt
(you may also need the other parameters which are listed in the
casLoginView.jsp)
4. Your HTTP response will be a redirect. You will need to retrieve the
service ticket from the redirect url.
Hope that helps.

Thanks for the response.
What I didn't get from your response is this- Is doing the GET/POST and parsing
the response a possible solution? My own knowledge about Spring etc is limited.
So, figuring out how to create a Controller and wire it into the framework may
turn out to be harder than doing a GET/POST and parsing the response. So, if it
is possible to do a GET/POST and parse the response, I would like some pointers
on how to do that.
Thanks.

If you want to do something like that I recommend creating a different endpoint
Controller that takes your parameters constructs the credentials and passes
them to an instance of CentralAuthenticationService which would allow you to
obtain a service ticket which you can return as the body of your response.
This gets around the whole parsing the GET and doing a POST to the normal
workflow.

I need to be able to authenticate a username/password combo received from a
legacy NON-webapp. From reading some of the old forum messages(
http://tp.its.yale.edu/pipermail/cas/2004-July/000617.html) , it seems I can do
a get/post to the CAS login servlet and parse the response for a service ticket
(not particularly appealing). Another method appears to be to use the
ServiceTicketValidator class and call validate() with a service ticket.
However, I am not sure how to get a service ticket in the first place (an
unused service ticket is what I need). The documentation for CASFilter and
CASValidateFilter indicate that these classes can be used to do validation but
I am not sure how (there don't seem to be any validate() kind of methods on
either of these 2 classes).
Can someone please clarify? If I am going to use the get/post method, what is
the name of the params to pass (Is ?username=xyz&password=abc ok?)
Thanks for your help.
