I have a NIS server and 16 NIS client. AIX 5.3 Installed in all the machine. Whenever I try to change my NIS passwd on any client machine using yppasswd it is giving the following error although I entered correct old NIS Password.
yppasswd: 1831-155 could not change passwd
In my Server yppasswd daemon is running ok. I restarted the passwd daemon but problem remains same. I can indirectly update password of user by changing passwd in the NIS server and running "cd /var/yp;make passwd".
