Lookup Manager

Ok, now I found something to get user accounts from a Sun's NIS server.
Is is called Lookup Manager. MacOS X uses "lookupd" as NextStep to get several information from a central server. Lookupd is compatible with SUN NIS (network information services). And this program allows you to configure the daemon. The thing is thar the users gotten from NIS are not recognized by the OSX. You have to add them in NetInfo. It is a mayor Bug and it is supposed to be fixed in 10.1.
