Tomcat: Realm, access to Request object

+1 vote
147 views

I write my own realm implementation for Tomcat 7.x. In the method Principal authenticate(X509Certificate[] certs) I'd like to read request headers. My authentication would be based on client certificate + custom http request value. Is it possible?

The method authenticate is called in
SSLAuthenticator.authenticate(Request request, HttpServletResponse response, LoginConfig config)

But I do not see that the Request object is passed to realm instance. Is there something similar like WebServiceContext that is used for WS?

...
 @Resource
 WebServiceContext wsctx;
 MessageContext mctx = wsctx.getMessageContext();
 HttpServletRequest request = (HttpServletRequest) 
mctx.get("javax.xml.ws.servlet.request");

In Tomcat, the Authenticator is responsible for gathering the credentials. This often requires interaction with the Request and related objects.

The Realm is responsible for validating credentials. Therefore the Realm does not need access to the Request and related objects.

In my web app, I'd like to re-use the (server-wide) Tomcat Realm that is already being used for HTTP Basic authentication but couldn't find a way how to get hold of the actual Realm instance.

I spent quite some time looking for a solution (complicated by the fact that most Google hits actually referred to the LDAP authentication realm) but found none. Is there a "config-file-only" solution or do I need to dig into the Tomcat source code and come up with my own JNDI ObjectFactory to achieve this ?

I want to access the JNDI Directory context in Tomcat8. I've used DirContextURLStreamHandler class which was in Tomcat 7. But now that has been removed.

Can someone tell me how can I access the JNDI Directory Context in Tomcat 8?

I'm running a server with multiple instance of tomcat each instance has some apps deployed & accessed with host:port, like

myhost.com:7777/app1
myhost.com:8888/app2
myhost.com:9999/app3

Is there any way to hide the port from users & making app URL simpler with keeping multi instance? like this or any thing near

app1.myhost.com
app2.myhost.com
app3.myhost.com

We have a set up like Apahce (80,443) redirects the request to Tomcat (8080) using mod_jk.

The new requirement is to route the request from the same apache to another tomcat (8090). Hence I made the different config file for apache with different ports (86,4444) and different worker for mod_jk which routes the request to tomcat.

Now the issue is when I hit the url http://:86 and after providing the credentials, it is redirecting to https://:86 and throwing the below error.

Error in browser:

Secure Connection Failed

An error occurred during a connection to x.x.x.x:86. SSL received a record that exceeded the maximum permissible length. (Error code: ssl_error_rx_record_too_long)

Error in logs:

Could you please suggest where it might went wrong and the way forward..
