I normally try not to ask questions until I have done as much research as possible, and again, this is the case... Just after I thought I had my RH5 samba/nis server working fine, I come across the inability to update nis passwords. >From the server as root: passwd guest1 Changing password for user guest1. New UNIX password: Retype new UNIX password: NIS password could not be changed. passwd: all authentication tokens updated successfully For the heck of it: yppasswd guest1 Changing NIS acount information for guest1 on server. Please enter root password: Changing NIS password for guest1 on server. Please enter new password: Please retype new password: Error while changing the NIS password. The NIS password has not been changed on the server. The server was rebooted, but that didn't help. What am I missing? Thanks. Scott
