/etc/yppasswd

Hi everyone.After a clean install, and when trying to add a new user with the user manager, I get the message "Error opening /etc/yppasswd for reading". I did "locate yppasswd" and found "etc/init.d/yppasswd" and went there and it was readable.I am unable to desipher it, but it is readable.However there were also about 8 others with "yppasswd" in the path. Does anyone have an idea?Thanks!! Donnie
