when attempting to install the groupwise gateway for microsoft exchange 7.02, i receive the following error:

error accessing domain database for selected domain. invalid or non-existant domain database.

the existing gw80 environment consists of a few sles 10 servers (mta, po, gwia, webacc) with edirectory 8.8 sp2, and an external bind dns. i've built a gateway system with the following components:

novell client 4.91sp5
c1 1.3.6h
gw801 mta

can anybody share tips for getting the gateway to see the domain database? are there installation logs i can check? are there any srv records that i need to verify are manually created in the bind dns? will i need microsoft's exchange connector for novell groupwise?
