> he can change passwords on the server at will. >From the rpc.yppasswdd manpage: The FreeBSD version of rpc.yppasswdd also allows the super-user on the NIS master server to perform more sophisticated updates on the NIS passwd maps. The super-user can modify any field in any user's master.passwd entry in any domain, and can do so without knowing the user's existing NIS password (when the server receives a request from the super-user, the password authentication check is bypassed). Furthermore, if the server is invoked with the -a flag, the super-user can even add new entries to the maps using ypchpass(1). Again, this only applies to the super-user on the NIS master server: none of these special functions can be performed over the network. The rpc.yppasswdd utility can only be run on a machine that is an NIS master server.Received on Sun Jun 15 2003 - 05:18:38 UTC
