I got two responses, both of which suggested trouble-shooting techniques.
I didn't try them because I had figured out the answer myself already.

The solution:
It turns out that newer versions of Solaris do not allow root to change
NIS* passwords. From man passwd(1) in Solaris 2.5.1 and later:
In the files case, superusers (for instance, real and effec-
tive uid equal to 0, see id(1M) and su(1M)) may change any
password;
But, from man passwd(1) in Solaris 2.4 the same section reads:
Super-users (for instance, real and effective uid equal to
zero, see id(1M) and su(1M)) may change any password;
So, in 2.5 or 2.5.1 this root power was rescinded. Nice of them to
document it so well. :-(
The original question:

The suggestions:
Arthur Darren Dunham <add@netcom.com>:
Try trussing yppasswdd. That may be more enlightening.
anders@hmi.de (Thomas Anders):
Is rpc.yppasswdd running on the same server? If not, snoop the
network traffic and look at the rpc.yppasswdd output on the server.
