Hey, guys,
I am pretty much a newbie for CAS. Recently I am trying to integrate some
client applciation with CAS server. I have pulled code from JASIG's svn and
added a customized Authentication Handler class, and then generate a war file
for CAS. The deployment of CAS is very smooth. I also configed keystore and
ssl on the server which CAS is running on, and seems it runs well. For now I
have two applications as client for testing. One is a very simple web
application, with just one index.jsp page, which print out the remote user's
name. This one works very well: it redirect to CAS login page, and after I
input user name and password, I can tell it processes the authenticate though
my own authentication Handler, and return the user name to my page.
The second one, which I have problem with, is a testing
client application from Spring securtiy.
I think it is a simple application as well, except it use spring securtiy
integrate with CAS. In it applicationContext-security.xml, there are some
config like:
<sec:user-service id="userService">
<sec:user name="jeyakumaran" password="rod"
authorities="ROLE_USER, ROLE_SUPERVISOR" />
<sec:user name="david" password="david" authorities="ROLE_USER"
/>
<sec:user name="scott" password="scott" authorities="ROLE_USER"
/>
</sec:user-service>
I have no idea what this for. The application runs well: when I type in
http://myhost.org:7001/casclient1, it redirect to cas login page. The
interesting thing is: if I try to login in as david/david, then I got the
credential error page. I think this is because I am using a customized
authentication Handler to process authentication. But, if I login as
tcloss/password, which is in my database, then I got error like: Your CAS
credentials were rejected. Reason: Could not find user: tcloss
I believe it is something about that <sec:user-service id="userService">
setting: if I add my user name to sec:user, then the error gone! But I totally
i have no idea about the reason. Could you please give me some advice about
this? Also, I was trying to access following link:
https://myhost.org:7002/cas/services and it gives me same Authorization Failure
error. How can I access to this?
Any suggestion is higly appreciated! And I do appreciate you guys for squazing
your precious time reading this. Thanks again!

| deployerConfigContext.xml centralizes into one file some of the
declarative configuration that
| all CAS deployers will need to modify.
|
| This file declares some of the Spring-managed JavaBeans that make up
a CAS deployment.
| The beans declared in this file are instantiated at context
initialization time by the Spring
| ContextLoaderListener declared in web.xml. It finds this file
because this
| file is among those declared in the context parameter
"contextConfigLocation".
|
| By far the most common change you will need to make in this file is
to change the last bean

SimpleTestUsernamePasswordAuthenticationHandler with
| one implementing your approach for authenticating usernames and
passwords.

two purposes. First, it uses them to identify the Principal

kind of credentials than UsernamePasswordCredentials, you will need to replace
| DefaultCredentialsToPrincipalResolver with a
