I'm developing a custom AuthHandler for our company. The idea is to allow access based on user and service. But i can't find a way to access the RegistredService.
Is there a way to pass the RegistredService to my AuthHandler ?
/**
* Mbox Auth Handler
*/
package lu.ion.cas.adaptors.mbox;
import org.jasig.cas.authentication.handler.support.AbstractPreAndPostProcessingAuthenticationHandler;
import org.jasig.cas.authentication.handler.AuthenticationException;
import org.jasig.cas.authentication.principal.Credentials;
import org.jasig.cas.authentication.principal.UsernamePasswordCredentials;
import lu.ion.cas.MboxAuthHelper;
import javax.validation.constraints.NotNull;
public class AuthHandler
extends AbstractPreAndPostProcessingAuthenticationHandler {
private MboxAuthHelper mboxAuthHelper;
private RequestContext context;
protected boolean doAuthentication(final Credentials credentials)
throws AuthenticationException {
return authenticateUsernamePasswordInternal((UsernamePasswordCredentials) credentials);
}
protected boolean authenticateUsernamePasswordInternal(
final UsernamePasswordCredentials credentials)
throws AuthenticationException {
return mboxAuthHelper.load(credentials.getUsername(), credentials.getPassword(), "/auth/check") != null;
}
public boolean supports(Credentials credentials) {
return true;
}
public final void setMboxAuthHelper(final MboxAuthHelper mboxAuthHelper) {
this.mboxAuthHelper = mboxAuthHelper;
}
}
I'm using CAS 3.5.2.
I have used CAS for a few years and found that there are many ways to do everything. I don't know how (or if) you can pass the RegisteredService to your AuthHandler. I solved the same problem by using a custom AuthenticationFilter.
(backend) Create AuthenticationFilter.java in/near your CAS project like this:
public class AuthenticationFilter implements Filter {
@Override
public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
HttpServletRequest request = (HttpServletRequest) req;
HttpServletResponse response = (HttpServletResponse) res;
HttpSession session = request.getSession();
String loginName = request.getRemoteUser();
String contextPath = request.getContextPath();
System.err.println("loginName is: " + loginName);
System.err.println("contextPath is: " + contextPath);
boolean isAuthorized = false;
// do work/query to find out if they are authorized
if (isAuthorized) {
chain.doFilter(request, response);
} else {
session.invalidate();
// print error page
}
}
@Override
public void init(FilterConfig config) throws ServletException {
}
@Override
public void destroy() {
}
}
(frontend) Then add to your filter chain. If you have a web.xml with existing CAS filters, it is easy.
...
<filter>
<filter-name>Custom Filter</filter-name>
<filter-class>
com.yoursite.filter.AuthenticationFilter
</filter-class>
</filter>
<filter-mapping>
<filter-name>Custom Filter</filter-name>
<url-pattern>/index.jsp</url-pattern>
</filter-mapping>
...
No there is no way to do this. If you want to implement authorization rules for CAS 3.5.2, you should review cas-addons: https://github.com/Unicon/cas-addons/wiki
