the question I posted last week was:
Question> we have several Suns running OS4.1 in two domains. We are
Question> desperatly trying to import into domain2 a NFS-filesystem
Question> that is exported secure in domain1. After reading the
Question> manuals, I thought that it would be sufficient to make the
Question> publickeys known across domains. So I added
Question> unix.host1@domain1 to the netid-file of domain2 and the
Question> publickey of unix.host1@domain1 to the publickey-file of
Question> domain2 and vice versa. But still I get an authentication
Question> error.
Question> Why? I mean, what do hosts within a domain know of each
Question> other except their publickeys?
The answer is simple, but very disappointing:
