Windows Authentication against multiple domains

[kbpo4]

Hi,
 
I am having a tomcat webapplication and logon needs to be done via
windows-authentication (ldap). I configured authentication against ldap,
that works fine for one domain. The problem is, that we are having users in
multiple domains. Is there a way to configure authentication against the
whole active directory forest?
 
Thanks for your help!
