I have a test environment running Fedora 8 and Samba 3.0.28 on two PDC's and one Domain Member. I am testing file-sharing across domains. I have a DOM-A PDC with a ldap backend. I have a DOM-B PDC with a ldap backend. The two domains have trusts both ways. I also have a domain member called TESTSERVER joined to the DOM-B domain running winbind. My DOM-B localsid is S-1-5-21-4183003764-1519580533-2309214288, and I set TESTSERVER to the same localsid and start winbind. When I do wbinfo -u, winbind core dumps. So I tried setting TESTSERVER to a different localsid and starting winbind and Samba, when I try connect to a share on TESTSERVER I see "tree connect failed: NT_STATUS_ACCESS_DENIED". I checked the the smbd log and I see the message "User test with invalid SID S-1-5-21-4183003764-1519580533-2309214288-1010 in passdb". So my question is what should the localsid be on TESTSERVER. Any help would be appreciated. Mike Cauble
