Link User Management ABAP-Java Stack

Hello everybody,

we have a WAS 6.40 ABAP+Java running. In client '000' if i create a new user, this user is also available at the java stack of the WAS. But if i create a new user in client 'XXX' (a copy of the client '001') it does not show up at the Java Stack. So there has to be some customizing settings i missed to set. Anyone can give me a hint?

thx

Markus
