Some years later.. 

How I get to change the user password with yppasswd for username as root;

1. Edit the /etc/yp/shadow and remove the password field of the user.
2. Save and close.
3. Run yppasswd username again.


Example:

If I were to change the password of henryk, I would do as follows;

1. Change the entry for the user at /etc/yp/shadow
henryk:dsdkljHjshd3KsaEd:51265::::::
to
henryk::51265::::::

2. Save and close.
3. Run yppasswd henryk

As this fails silently (no traces on /var/log/messages, /var/log/scure) of what went wrong, I resulted here...

In my particular case, the user to have its password changed had it actually disabled inside /etc/shadow such as:
johndoe:!!:16050:0:120:7::17896:

So as per santiag's hint I edited the shadow file (vipw -s) and removed the !! signs... then yppasswd worked as needed.

Just my 1 cent here...

Hi there,

I've had the same issue just now and we fond that our new NIS server did not have correctly configured YPPWDDIR in the /etc/default/nis and was not pointing at our passwd file. For that reason it was silently failing. 

Best, Mat

See, this is why most of us filter out anything coming in through
