Binding to Multiple Directories

I am having difficulty binding clients to multiple open directory servers. All clients are running Lion. This issue did not occur under Snow Leopard. The servers are both Mac OS X Servers running Open Directory. There are two domains to which the client is successfully bound (DomainA and DomainB). If a user attempts to login using credentials from DomainB, they log in successfully but home folders are "not in the expected location" - so no data is present. If I unbind the client from DomainA and then attempt to login using credentials from DomainB, the issue is resolved. Is there a way to set a priority for how the client binds?
