Netinfo questions

Howdy, I've got an OSX server 10.28 running as my main user server. I'd like to have other servers OSX/Solaris9/Debian3 use my primary OSX server for users, but not sure how to go about that. I've pointed the second OSX server at the primary netinfo server, and I get a 127.0.0.1 netinfo db not found error on boot. So I can't log into that machine as a user. I'm pretty sure that with solaris and debian I'll need to futz with OpenDirectory or some such, but want to sort netinfo to netinfo first. thanks ST
