Dear Ian Thanks for the message and that works well for us. But how passwd changes nis passwd? i have read the man page for passwd and in the Internet, nowhere said passwd can change nis passwd, so never even thinking of trying this way. Still i need to know how this happens and would be most grateful if you can brief let me know more. thanks cheng --- Ian Mortimer <ian@xxxxxxxxxxxxxxxxx> wrote: > On Wed, 2005-01-12 at 21:38, zhicheng wang wrote: > > > if the passwd is created/changed on the nis server > > using passwd, it is ok and can be very long (up to > > 256char?) and users have to type exactly the > correct > > passwd to log in - no longer, no shorter. > > > > if users change their passwd using yppasswd, the > > passwd is truncated to 8 char and you can type > > anything after the 8th char to log on. > > If you have the client hosts set to do md5 > encryption and use passwd to > change the password it will create an md5 encrypted > password in the nis > database. yppasswd always seems to create crypt > encrypted passwords > (and they can only be 8 characters or less). > > If passwd works then you can just disable yppasswd > and make your users > use passwd. > > However if you have any systems on your network that > don't understand > md5 encrypted passwords your users won't be able to > authenticate to > those systems after changing their passwords. > > > -- > Ian > ===== Best wishes Z C Wang ___________________________________________________________ ALL-NEW Yahoo!
