Security Context Propagation

Hi,

I have an enterprise app installed under weblogic 8.1 that uses J2EE security. We log into the web container (j_security_check), the security context (SC1) is properly propagated to the ejb container. So far so good.

From an EJB, I must call another EJB in a remote application server that is Weblogic 7.0.4. To do this I explicitely specify the parameters to open the InitialContext on the remote server. These parameters are Context.PROVIDER_URL, Context.INITIAL_CONTEXT_FACTORY, Context.SECURITY_PRINCIPAL and Context.SECURITY_CREDENTIALS.

The remote weblogic server does not know the security context in the local weblogic server (SC1), this is why I specify the principal/credentials pair that is valid on the remote server.

I can create the InitialContext, I can lookup the Home interface of the EJB in the remote server, but when I call homeObj.create() to create a Stub to an EJB instance, the remote server throws a "java.lang.SecurityException: Invalid Subject, principals=[<principals from the local weblogic server>]".

Which means that the local security context is propagated to the remote weblogic server, although I have explicitely specified it as the parameters to the InitialContext.

Can anybody help me to solve this problem?

Thanks in advance, I hope the above description is clear enough.

Tibor

Uhhm. Did you close the remote jndi context after the look up on the remote machine? If you have closed it, then yes, the local user credentials will be passed.
