Security with Tomcat on a different machine

[zzzz]

Hi everybody,

I'm using JBoss2.4.3 with Tomcat3.2.3 and Form based authentication. I have a web application with EJB's. Everything works fine when the jar and the war files are on the same machine. When the war file resides on a different machines the user can't log in. I put all the jar files from
JBOSS_DIST/jboss/client in the folder TOMCAT/lib of the remote machine but it does not solve the problem.On the first machine I have only Tomcat3.3a and on the other JBoss with Tomcat.

Any ideas? Thanks in advance!
