root can't change user-passwords

[Karl Bongartz]

Hello
we have installed HPux11 on a E55 Server.
When i want to change user-passwords as root user, i am always prompted for the users old-Password.
root uid is 0, the access rights for etc/passwd are same as on a 10.20 System?
The system is not setup as trusted System.
Has anyone an idea who to solve this Problem?

Hi there.
edit the /etc/passwd. Replace the combination in the second column ( 13 characters ) by the combiantion ,..
Then the user will be asked to enter a new password on next login.

Do you implement the NIS/NIS+ in your system ? If yes, this will happen .

logout and login.

Hi,
you can do this using SAM

hello,
the machine is setup as NIS Server.
nevertheless it should be possible for the root user, to change passwords of other users, without entering the users old password (which root does not know).

Hi Karl,
I think if you have password setup then passwd will ask you for your old password. So you have to remove second field from passwd file manually then it will ask you for new password.

Hi Karl,

Since you are using NIS, yppasswd always prompts for the old passwd even if the effective uid is 0. The undeylying function (yppasswd) requires the old passwd as an argument. However, you can as root on the NIS server use 'passwd' (not yppasswd) to change the passwd of any user. You then need to push the new passwd map either by
cd'ing to /var/yp amd 'make' or with an explicit ypmake command.

This should fix you, Clay

i have testet and found, that /sbin/passwd
sets the password without prompting for the old one

regards and thanks for your help
