Information update.

I found something strange. I turned ypserv debug mode on, then It seemed ypserv recognized NIS domain and tried to find the user info, however, it did check passwd.adjunct.byname and then skipped and kept searching info from shadow.byname.

I tried to copy /var/yp/`domainname`/passwd.adjunct.byname to /var/yp/`domainname`/shadow.byname and re-login from NIS master again, and it worked.

I just don't know why is that? It supposed to authenticate a NIS user just like the client did.

This is ypserv debug log as below, I'm kind of week analyzing this log, maybe someone can help to find the key.
Code:
# ypserv -d
[ypserv (ypserv) 2.19]
