Hi all
have a problem with CAS and LDAP...
My web browser displays :
type Informe de Excepción
mensaje
descripción El servidor encontró un error interno () que hizo que no pudiera
rellenar este requerimiento.
excepción org.springframework.context.ApplicationContextException: Unable to
initialize application context.
org.jasig.cas.web.init.SafeDispatcherServlet.service(SafeDispatcherServlet.java:117)
nota La traza completa de la causa de este error se encuentra en los archivos
de diario de Apache Tomcat/5.5.23.
I have read the forum...
I have tried to start cas with SSL (with the certificated)...
%JAVA_HOME%\bin\keytool -delete -alias tomcat -keypass
changeit%JAVA_HOME%\bin\keytool -genkey -alias tomcat -keypass changeit -keyalg
RSA%JAVA_HOME%\bin\keytool -export -alias tomcat -keypass changeit -file
%FILE_NAME%%JAVA_HOME%\bin\keytool -import -file server.crt -keypass changeit
-keystore %JAVA_HOME%/jre/lib/security/cacerts%JAVA_HOME%\bin\keytool -import
-file server.crt -keypass changeit
without SSL :
1. In the cas-servlet.xml, the two cookie generators need the "secure"
property set to false.
2. If you plan on doing proxy callback to clients without SSL, the
HttpBasedServiceCredentialsAuthenticationHandler needs to be configured to
allow non-https urls. Its a property on the handler.
I have added all libraries
and my deployerConfigContext.xml :
<?xml version="1.0" encoding="UTF-8"?>

| 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
| declaration to replace the default
SimpleTestUsernamePasswordAuthenticationHandler with
| one implementing your approach for authenticating usernames and passwords.
+-->
<beans>
<!--
| This bean declares our AuthenticationManager. The
CentralAuthenticationService service bean
| declared in applicationContext.xml picks up this AuthenticationManager by
reference to its id,
| "authenticationManager". Most deployers will be able to use the default
AuthenticationManager
| implementation and so do not need to change the class of this bean. We
include the whole
| AuthenticationManager here in the userConfigContext.xml so that you can see
the things you will
| need to change in context.

<bean id="authenticationManager"

<!--
| This is the List of CredentialToPrincipalResolvers that identify what
Principal is trying to authenticate.
| The AuthenticationManagerImpl considers them in order, finding a
CredentialToPrincipalResolver which

|
| AuthenticationManagerImpl uses these resolvers for two purposes. First, it
uses them to identify the Principal
| attempting to authenticate to CAS /login . In the default configuration, it
is the DefaultCredentialsToPrincipalResolver
| that fills this role. If you are using some other kind of credentials than
UsernamePasswordCredentials, you will need to replace
| DefaultCredentialsToPrincipalResolver with a CredentialsToPrincipalResolver
that supports the credentials you are
| using.
|
| Second, AuthenticationManagerImpl uses these resolvers to identify a service
requesting a proxy granting ticket.
| In the default configuration, it is the
HttpBasedServiceCredentialsToPrincipalResolver that serves this purpose.
| You will need to change this list if you are identifying services by
something more or other than their callback URL.

| UsernamePasswordCredentialsToPrincipalResolver supports the
UsernamePasswordCredentials that we use for /login
| by default and produces SimplePrincipal instances conveying the username from
the credentials.

| If you've changed your LoginFormAction to use credentials other than
UsernamePasswordCredentials then you will also
| need to change this bean declaration (or add additional declarations) to
declare a CredentialsToPrincipalResolver that supports the
| Credentials you are using.

| HttpBasedServiceCredentialsToPrincipalResolver supports HttpBasedCredentials.
It supports the CAS 2.0 approach of

Credentials and representing it as a
| SimpleService identified by that callback URL.

| If you are representing services by something more or other than an HTTPS URL
whereat they are able to

add additional declarations).

<!--
| Whereas CredentialsToPrincipalResolvers identify who it is some Credentials

AuthenticationHandlers that

identified. CAS will try these handlers in turn
| until it finds one that both supports the Credentials presented and succeeds
in authenticating.

LDAP search-and-bind authentication
This method first searches the user.s node in the directory. When it finds the
user it attemps to do a bind with the user.s node DN that resulted from the
search and the password from the user's submitted credentials. Note that for
this method you will need a special user that is allowed to search the
directory (OR allow anonymous access to search the directory).
To configure this CAS AuthenticationHandler, open the
${project.home}/webapp/WEB-INF/deployerConfigContext.xml and edit the
authenticationHandlers property list to make it look like this:

<property name="authenticationHandlers">

The filter property is the LDAP filter that will be used for the search. The
"%u" will be replaced by the userName from the credentials.
The search base is the node in the directory from where the search will be
performed.
The contextSource property is a reference in this example. The contextSource
property is a reference in this example. This means you should define another
bean in the top level list of beans (add it at the bottom of the same file,
right before the </beans> tag), here's an example.
