broken nis in rawhide?

["Dr. Michael J. Chudobiak" <mjc avtechpulse com>]

Is there some reason why rawhide's ypbind should fail to bind, if I have 
nsswitch.conf =

passwd:     files nis
shadow:     files nis
group:      files nis

<other stuff snipped>

This worked fine on F10, and it works OK if I downgrade to the F10 
ypbind rawhide. But with the rawhide version, the nis server reports 
errors like this:

Feb  2 14:15:28 server2 ypserv[2312]: refused connect from 
192.168.0.89:56329 to procedure ypproc_match (nisavtech,shadow.byname;-1)


Has something changed with nis sharing of shadow password data?
