passwd change on NIS setup

Hello,

I have a setup where a NIS server is supplied by an AIX v6 system.
My desktop clients are running openSUSE v13.2 configured via autoyast.


  <nis>
    <nis_broadcast config:type="boolean">false</nis_broadcast>
    <nis_broken_server config:type="boolean">false</nis_broken_server>
    <nis_local_only config:type="boolean">false</nis_local_only>
    <nis_domain>DOMIAN</nis_domain>
    <nis_servers config:type="list">
      <nis_server>192.168.xxx.xxx</nis_server>
    </nis_servers>
    <start_nis config:type="boolean">true</start_nis>
  </nis>

The login works fine, however, when I run ‘passwd’ as non-privileged user I receive


passwd: User not known to the underlying authentication module
passwd: password unchanged

and the ‘journalctl -x’ output tells me


Jun 30 17:16:58 sabancaya passwd[3392]: pam_unix(passwd:chauthtok): user "blut" does not exist in /etc/passwd

A successful login returns


Jun 30 17:19:08 sabancaya login[24768]: pam_unix(login:session): session opened for user blut by LOGIN(uid=0)
Jun 30 17:19:08 sabancaya login[24768]: LOGIN ON tty2 BY blut

I have pam-1.1.8-11.1.2 installed.
If you have any idea how I can enable users to change their password from the desktop, please let me know.

PS: ‘yppasswd’ has the following output


yppasswd is deprecated, use /usr/bin/passwd instead

passwd: User not known to the underlying authentication module
passwd: password unchanged
